CA3130 MOSFET BiMOS Op-Amp Datasheet, Pinout, Features & Applications
Hi Everyone! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to CA3130.
The CA3130 is a BiMOS Operational Amplifier that comes with MOSFET at the output. The term BiMOS suggests that it projects the advantage of both Bipolar and CMOS op-amp technology.
This IC comes with high bandwidth due to bipolar op-amps and consumes less current due to CMOS op-amp, making it a perfect fit for mobile jammers and voltage follower circuits.
I suggest you read this post all the way through as I’ll detail 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 contains MOSFET at the output. This chip consumes less current and features high bandwidth.
- This device has high input impedance due to MOSFETs which implies that when an output voltage of the sensor is connected to the inverting or non-inverting terminals of the op-amp, the output voltage from the sensor will not be disturbed since the op-amp will not act as a load to the sensor.
- If you’re looking for a device with high input impedance, less power consumption, and high bandwidth, this chip might be the answer.
- CA3130 is an eight-terminal electronic IC that comes with a Common Mode Rejection Ration (CMRR) of 80dB.
- It is widely used in frequency generators and noise detectors.
- The input terminal current of this device is 1mA and the supply current is 10mA.
- The CA3130 features inverting and non-inverting pins like other op-amps. If the voltage at the non-inverting pin is high, the output across the inverting pin will be high, otherwise, it will be low.
- Pins 1 & 5 are offset null pins used to nullify the offset produced when two input pins are combined. When the input pins of the op-amp are combined with each other, the voltage at the output should be zero. But no operational amplifier is ideally perfect. So when two inputs are combined together, it results in the offset. The offset null pins are used to null that effect.
- Pin 8 is called Strobe that is mainly used to turn off the output stage. It is also employed for phase compensation in comparators.

CA3130 MOSFET Op-Amp Datasheet, Pinout, Features & Applications
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.
- The rise time of this device is 0.09uS and the CMRR is 80dB which makes it an ideal pick for voltage followers and high-frequency applications.
