Improvements have been made over OP-07 specifications in several areas.Notable is bias current, which remains below 250pA over the full military temperature range.The OP-97 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 OP-97, at 114dB minimum over wider ranges of common-mode or supply voltage.Outstanding PSR, a supply range specified from ±2.25V to ±20V and the OP-97's minimal power requirements combine to make the OP-97 a preferred device for portable and battery-powered instruments.
The OP-97 conforms to the OP-07 pinout, with the null potentimeter connected between pins 1 and 8 with the wiper to V+.The OP-97 will upgrade circuit designs using 725, OP05, OP07, OP12, and 1012 type amplifiers.It may replace 741-type amplifiers in circuits without nullling or where the nulling circuitry has been removed.
