GENERAL DESCRIPTION
The OP297 is the first dual op amp to pack precision performance into the space saving, industry-standard 8-lead SOIC package. The combination of precision with low power and extremely low input bias current makes the dual OP297 useful in a wide variety of applications.

FEATURES
    Low offset voltage: 50 μV maximum
    Low offset voltage drift: 0.6 μV/°C maximum
    Very low bias current: 100 pA maximum
    Very high open-loop gain: 2000 V/mV minimum
    Low supply current (per amplifier): 625 μA maximum
    Operates from ±2 V to ±20 V supplies
    High common-mode rejection: 120 dB minimum

APPLICATIONS
    Strain gage and bridge amplifiers
    High stability thermocouple amplifiers
