OP97EPZ vs OP97EN8#PBF vs OP97FPZ Comparison

The OP97EPZ is a low power high precision Operational Amplifier maintains the standards of performance set by the OP07 while utilizing only 600µA supply current, less than 1/6 that of an OP07. Offset voltage is an ultralow 25µV and drift over temperature is below 0.6µV/°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 250pA 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 114dB minimum over wider ranges of common-mode or supply voltage. Outstanding PSR, a supply range specified from ±2.25 to ±20V and the minimal power requirements of the OP97 combine to make the OP97 a preferred device for portable and battery-powered instruments.
