低功耗，高精度运算放大器 LOW POWER, HIGH PRECISION OPERATIONAL AMPLIFIER
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.
