GENERAL DESCRIPTION

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 μA supply current, less than 1/6 that of an OP07. Offset voltage is an ultralow 25 μV, and drift over temperature is below 0.6 μV/°C. 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 below 250 pA over the full military temperature range. The OP97 is ideal for use in precision long-term integrators or sample-and- hold 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 minimal power requirements of the OP97 combine to make the OP97 a preferred device for portable and battery-powered instruments.

The OP97 conforms to the OP07 pinout, with the null potenti- ometer connected between Pin 1 and Pin 8 with the wiper to V+. The OP97 upgrades circuit designs using AD725, OP05, OP07, OP12, and PM1012 type amplifiers. It may replace 741- type amplifiers in circuits without nulling or where the nulling circuitry has been removed.
