Introduction to TL072
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to TL072. TL 072 is basically a high speed Junction Field Effect Transistor (JFET). It is also known as the dual operational amplifier. It has a bipolar transistor and high voltage JFET in its case. TL-072's important features include low offset current, high slew rates, low input voltage, low offset temperature coefficient etc.
Some of the major features may include low power consumption, low noise, common mode input voltage range includes Vcc, latch-up free operation etc. TL 072 has a very wide range of applications including oscilloscope, solar inverters, AC inverters and VF drives, audio mixers, Un-interruptable Power Supply (UPS) etc. Further detail about TL-072 will be given later in this tutorial.
