ADI OP97FSZ-REEL7

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/℃. External offset trimming is not required in the majority of circuits. 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 potentiometer 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.
