Where to use OP07 IC

The OP07 single operational amplifier offers a wide input voltage range of ±13 V minimum combined with a high CMRR of 106 dB and high input impedance to provide high accuracy in the noninverting circuit configuration. OP07 can maintain excellent linearity and gain accuracy even at high closed-loop gains. The OP07 has excellent Stability of offsets and gain with time or variations in temperature. These features made the OP07 an industry standard for instrumentation applications.

 

So if you are looking for an Op-Amp with wide input voltage range and higher stability and accuracy with temperature variations, then this IC might be the right choice for you.

 

How to Use OP07 IC

An Input Offset-Voltage Null Circuit from OP07 datasheet is given below. The input offset voltage of operational amplifiers caused by mismatched transistor pairs, collector currents, current gain betas (β), collector or emitter resistors, etc. These input mismatches can be adjusted by putting resistors or a potentiometer between the inputs as shown in the below circuit.

 

A 20K potentiometer is used between the offset null pins of the op-amp. This potentiometer is used to fine-tune the circuit during testing or for applications that require precision offset control.
