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 inverter, AC inverters and VF drives, audio mixers, Un-interruptable Power Supply (UPS) etc. The further detail about TL-072 will be given later in this tutorial.
Introduction to TL072
is a Junction Field Effect Transistor abbreviated as JFET
. Sometimes it is also known as dual operational amplifier. It has several different amazing features including low noise, low power consumption, high slew rates, latch-up free operation, low temperature coefficient. It can be used in UPS, audio mixers, solar inverters, oscilloscope, AC inverters etc. TL-072 is shown in the figure below.
