The OP07 is a very high precision op-amp with an offset voltage maximum of 150µV. Offering also low input current (1.8nA) and high gain (400V/mV), the OP07C is particularly suitable for instrumentation applications.

• The input offset voltage is very low. The maximum input offset voltage for OP07E is 75µV

• The range for the input voltage is ±14 V

• The range for supply voltage is from ±3 V to ±18 V CMRR is high. For OP07E, it is 106 dB

• It has high input impedance and provides a low-noise operation

• A wireless base station and optical networks

• Strain bridges

• Instrumentation

• Shunt current measurements

• Resistor thermal detectors (RTDs)

• Sensors and controls

• TL081

• RC4558

• NJM4560

Although the OP07  IC has a low input bias current and a large open-loop gain, it does not compromise gain accuracy and preserves linearity. These characteristics make the OP07  IC suitable for high-gain instrumentation applications.

To use the OP07  chip, turn it on by connecting the voltage supply. Depending on the application, it can run on a single supply or a dual supply. It has a maximum voltage rating of 22 volts. A voltage supply that is higher than this can irreversibly harm the chip. When both inputs of an operational amplifier are grounded, they should produce zero output, yet the inverting and non-inverting inputs are at different potentials in actuality.

Mismatched collector currents, current gain, collector resistor, emitter resistor, and other factors could be to blame. As a result, the OP07 provides two input offset pins that can be used to change the offset voltage via external circuitry to correct these mismatches. Normally, a  resistor or a potentiometer is connected between these input pins. You can set the desired value by altering the resistance of a potentiometer. The potentiometer is mostly used in applications where accurate offset control is required. The output voltage of the OP07 amplifier is limited to 12 V by the internal circuit. The circuit for setting input offset voltage is shown below.
