OP97

The OP97 is a low power alternative to the industry-standard OP07 precision amplifier. The OP97 maintains the standards of performance set by the OP07 while utilizing only 600 A supply current, less than 1/6 that of an OP07. Offset voltage is an ultralow 25 V, and drift over temperature is below 0.6 V/.

External offset trimming is not required in the majority of circuits. Improvements have been made over OP07 specifications in several areas. Notable is bias current, which remains below250 pA over the full military temperature range. The OP97 is ideal for use in precision long-term integrators or sample-andhold circuits that must operate at elevated temperatures.

Common-mode rejection and power supply rejection are also improved with the OP97, at 114 dB minimum over wider ranges of common-mode or supply voltage. Outstanding PSR, a supply range specified from ±2.25 V to ±20 V and the OP97's minimal power requirements combine to make the OP97 a preferred device for portable and battery-powered intruments.

The OP97 conforms to the OP07 pinout, with the null potentiometer connected between Pins 1 and 8 with the wiper to V+. The OP97 will upgrade circuit designs using 725, OP05, OP07, OP12, and 1012 type amplifiers. It may replace 741-type amplifiers in circuits without nulling or where the nulling circuitry has been removed.
