The KA3525A is a monolithic IC chip that features the control circuitry mainly required for a pulse width modulating regulator. This device comes with an error amplifier, voltage reference, pulse width modulator, an under-voltage lockout, an oscillator, the output driver, and a soft start circuit, all in one package.

I suggest you buckle up as I’m going to discuss the complete introduction to KA3525A covering datasheet, pinout, features, and applications. Let’s jump right in.

Introduction to KA3525A

• The KA3525A is a monolithic IC chip that incorporates the control circuitry used for pulse width modulation.
• During the PWM process, the control circuit inside the chip generates variable-width pulses against the amplitude of the input analog signal.

• The PWM is a technique that reduces the power produced by the electrical signal by converting it into discrete several parts. Thus, controlling the value of current or voltage by the switch. This switch is located between the supply & load and controls the value of the input signal when we turn it ON and OFF at a fast rate.

• The term duty cycle is associated with this PWM which is defined as the proportion of ON time of the entire input signal. If the signal remains 10% ON and 90% OFF, then the duty cycle tends to be 10%. If the signal remains 50% OFF and 50% ON, then the duty cycle is said to be 50%.

• This is a 16-pin chip that requires a supply voltage of around 40V and features a reference output current of around 50mA.
• The operating temperature ranges from 0 to 70 C while the storage temperature ranges from -65 to 150 C.
• Power dissipation is 100mW and the output sink current is 500mA.
• This pulse-width modulation regulator IC incorporates 16 pins.
• This device generates two PWM signals that are a complement to each other.
• This component is widely used in switch-mode power supply and other electronic circuits.
• The output voltage is controlled by feedback circuitry that does it by comparing the feedback signal with a reference voltage.
• This device features a shutdown protection circuit that turns off the PWM signal if the feedback signal reaches its limit.

• Pin 3 is employed for the synchronization of two waves while Pin 4 is the output pin of an oscillator.
• Pins 5, 6 & 7 are incorporated to adjust the frequency of PWM.
• We can control the frequency of PWM by controlling the value of the discharge resistor, CT capacitor, and RT resistor.
• Pin 8 SS is a soft start pin that enables the output signal after some time. The value of capacitance is directly related to the soft-start time.
• Pin 9 is called a compensation pin employed to prevent rapid fluctuations in the output voltage signal.
• Pin 10 is known as a shutdown pin. It shuts down the PWM signal when the current reaches its limit.
• Pins 11 and 14 are known as the output pins used to provide input to the MOSFETs. KA3525A incorporates a built-in MOSFET driver circuit.
• Pin 13 and 15 are called the power pins. Vc should range from 5-35 volts while Vin should stand between 8-35 volts.

Hello Friends! Hope you’re well today. I welcome you on board. Thank you for clicking this read. In this post today, I’ll detail the Introduction to CA3130.

The CA3130 is a BiMOS Operational Amplifier that comes with MOSFET. BiMOS is a term that defines the combination of both CMOS and bipolar op-amp technology into a single integrated circuit. CMOS op-amp is highly efficient and consumes less current while bipolar op-amp carries high bandwidth. Overall CA3130 is a device that combines the advantages of both bipolar and CMOS op-amp means it consumes less power and carries high bandwidth.

I suggest you buckle as I’ll discuss the complete Introduction to CA3130 covering datasheet, pinout, features, and applications. Let’s get started.

Introduction to CA3130

• The CA3130 is a BiMOS Operational Amplifier that incorporates MOSFET. It is widely used in Mobile jammers and oscillator circuits.
• Incorporated in a frequency generator, CA3130 carries an input terminal current of around 1mA and a maximum output voltage of around 13.3V.

• The common-mode rejection ratio of this device is 80 dB. This rejection ratio is the ability of the device to turn down common-mode signals. It is a ratio between differential mode gain and common-mode gain.

• The CA3130 comes with high input impedance due to the presence of built-in MOSFETs. This also projects when the output voltage of the sensor is attached to the non-inverting and inverting pin of the op-amp, the resulting output voltage of the sensor doesn’t change its value.
• If you are pondering for a device with less power consumption, fast sample rate, high input impedance, and high bandwidth, then this CA3130 op-amp might be the right fit for you.

How to Use CA3130

• CA3130 carries both inverting and non-inverting pins.
• The non-inverting pin is directly related to the inverting terminal and the output pin means when the voltage at the non-inverting pin is high then both the inverting pin and output pin will be high.
• The CA3130 operates as a single supply voltage with a range of 5V to 16V and as a dual supply mode with a range of ±2.5V to ±8V.
• Here in this example, we will take a single supply voltage with a power supply of 5V, as this is the most commonly used circuit.
• In this circuit design, the pin 8 Vcc is attached to the 5V voltage supply while pin 4 is grounded where the potential difference is zero. A sample CA3130 circuit is given below.

I suggest you go through this entire post till the end, as I’ll detail the Introduction to SB560 covering datasheet, pinout, features, and applications. Let’s jump right in.

Introduction to SB560

• The SB560 is a Schottky diode used in extremely fast switching applications. It is also known as a hot-carrier diode.
• When semiconductor material combines with the metal, they generate Schottky diode. This diode is a two-terminal device where these terminals are used for the external connection with the circuit.

• One terminal is known as anode made of metal material while the other terminal is called cathode made of semiconductor material.

• The anode side is positive while the cathode side is negative. And current only flows in one direction. This diode blocks the current in the opposite direction. The current flows from the anode pin to the cathode pin.
• This Schottky diode is also known as a hot-carrier diode. In an unbiased condition, this device possesses low electronic energy that results in the construction of a barrier that restricts the movement of electrons. Due to the formation of this barrier, Schottky diodes are also called hot-carrier diodes.
• Schottky diode and common diode operate in a similar fashion considering the flow of current. Both favor current flow in one direction and restrict the current flow in another direction. These devices are different considering the voltage required to power up these diodes.
• Though both devices require 2V DC source voltage, the Schottky diode needs only 0.3V, leaving behind 1.7V to supply power to the diode. While common diode needs only 0.7V, leaving behind 0.3V to supply power to the diode.

• Schottky diode is formed when the semiconductor material is joined with metals like tungsten, platinum, chromium, and molybdenum.
• When these two materials are joined they constitute a barrier that blocks the movement of electrons.
• Recall, the formation of a barrier is due to the low electronic energy in the unbiased condition.
• Commonly, the n-type semiconductor material is used to form the Schottky diode.
• P-type semiconductor materials are also used for making the Schottky diode but they are not preferred over n-type semiconductor materials because the former comes with low forward drop voltage.
• The anode side of the diode is composed of metal while the cathode side is made of semiconductor material. And current flows from the positive anode side to the negative cathode side.

TL084 Op-Amp Datasheet, Pinout, Feature & Applications

Hi Guys! Hope you’re well today. I welcome you on board. Happy to see you around. In this post today, I’ll detail the Introduction to TL084. TL084 is a JFET input Op-Amp that carries low offset current and high input impedance. Available with better offset characteristics and high noise immunity, TL084 comes with a suitable offset voltage that makes it an ideal pick for amplifier applications. I suggest you read this post all the way through as I’ll walk you through the complete Introduction to TL084 covering datasheet, pinout, features, and applications. Without further ado, let’s get started.

Introduction to TL084

• The TL084 is available in Quad Package which means it comes with four separate op-amps that can operate independently.
• This op-amp carries low noise and harmonic distortion that makes it an ideal pick for the audio pre-amplifiers.

• The bipolar transistors and high-voltage JFET are incorporated that are responsible for the device's low bias current and high input impedance.

• Previously, I’ve uploaded Introduction to LM324 op-amp that is almost similar to TL084 as both are available in quad package and carry four op-amps inside.
• Both operate in a similar manner, however, the area where they differ is the voltage required for the working of these op-amps. The TL084 requires 7 V for its operation while LM324 requires a common 5V supply to put it in running condition.
• While using TL084, make sure you terminate the unused op-amp in this Quad package. Since, if not terminated, they might develop some stay capacitance that can get some noise, hence affecting the overall performance of this device.
• Moreover, unused op-amp utilizes more power, thus decreasing the device efficiency.

TL084 Internal Design

• Op-amps are famous for their high input impedance which means it doesn’t distort the initial signal applied to the input pin.

• The op-amp input stage is considered as the most complex stage of the amplifier, because if handled inappropriately, it may result in the damage of the entire circuitry.
• While working with the supply voltage signals make sure, the voltage applied to the input pin should never exceed the rail voltage else it will generate a short circuit by producing the latch-up condition.
• Moreover, the differential input voltage rating must be higher than the voltage difference between the inverting and non-inverting pins.

• It is important to note that TL084 is not a rail to rail op-amp which means output voltage will not be reaching the maximum negative or maximum positive value when the device is saturated.
• You will always get the 2V less than the supply voltage due to the voltage drop occurred by the transistors inside the op-amp.
• Op-amps carry a very large open-loop gain but this gain is commonly occupied with the noise, the reason most circuits are designed using closed-loop gain.
• The closed-loop gain works in such a way it keeps feeding the input signal with the feedback signal which results in the restriction of gain value and the noise accompanied by it.
• Know that… negative feedback is preferred over positive feedback due to its stable and predictable behavior.

TL084 Datasheet

While incorporating this device into your electrical project, it’s wise to have a look at the datasheet of the component that details the main characteristics of the component. You can download the datasheet of TL084 by clicking the link below.

Hello Friends! Happy to see you around. I welcome you on board. In this post today, I’ll walk you through the Introduction to 1n4742.

The 1n4742 is a Zener diode used for clipping circuits with a high power rating. It is made up of silicon material and comes in the DO-41 package. The Zener diode conducts in both directions i.e. forward-biased condition and reverse-biased condition.

Introduction to 1N4742

• The 1n4742 is a Zener diode that comes in the DO-41 package. It is made up of semiconductor material and is mainly used for clipping circuits with high power ratings.
• There is a difference between a diode and a Zener diode. The simple diode conducts in one direction only i.e. forward biased condition. The current flows from the anode terminal to the cathode terminal.
• Zener diode conducts in both conditions i.e. forward biased condition and reverse biased condition.
• If we force a normal diode to conduct in both directions, it will result in damage to the component.

• The Zener diode is constructed by plenty of different voltages and is considered as a building block of modern electronics.
• Some Zener diodes carry highly doped and sharp p-n junction where reverse conduction is carried out by the electronic quantum tunneling process also known as Clarence Zener or Zener effect.

• Zener diodes are employed to produce low-power supply rails using higher voltages. They are also used to generate reference voltages for the electrical circuits.
• Zener diodes are also incorporated to keep circuits from overvoltage.
• You need to consider two parameters while selecting the Zener diode. The power dissipation and Zener voltage. The Zener voltage potential is achieved when a certain higher reverse voltage is applied to the Zener diode.
• The amount of current flow inside the Zener diode is demonstrated by the power dissipation. More dissipation results in more current flow. Power dissipation is 1W in this 1n4742 Zener diode.
• The Zener resistor is also employed in the electrical circuits along with the Zener diode that mainly works to limit the current flowing through the diode and the load connected to the Zener diode.
• The Zener resistor prevents the Zener diode from high current. In the absence of this resistor, the Zener diode would be damaged due to the high current passing through the diode.
