GENERAL DESCRIPTION. The OP97 is a low power alternative to the industry-standard Common-mode rejection and power supply rejection are also OP07 Precision amplifier .

2 The OP97 maintains the standards of improved with the OP97, at 114 dB minimum over wider performance set by the OP07 while utilizing only 600 A supply ranges of common-mode or supply voltage. Outstanding PSR, a current, less than 1/6 that of an OP07. Offset voltage is an ultralow supply range specified from V to 20 V, and the minimal 25 V, and drift over temperature is below V/ C. External power requirements of the OP97 combine to make the OP97 a offset trimming is not required in the majority of circuits. preferred device for portable and battery-powered instruments. Improvements have been made over OP07 specifications in The OP97 conforms to the OP07 pinout, with the null potenti- several areas.

3 Notable is bias current, which remains below ometer connected between Pin 1 and Pin 8 with the wiper to 250 pA over the full military temperature range. The OP97 is V+. The OP97 upgrades circuit designs using AD725, OP05, ideal for use in Precision long-term integrators or sample-and- OP07, OP12, and PM1012 type amplifiers. It may replace 741- hold circuits that must operate at elevated temperatures. type amplifiers in circuits without nulling or where the nulling circuitry has been removed. Rev. G.
