Chopper-Stabilized Op Amps Low-leakage, high-impedance CMOS inputs allow the ICL7650/ICL7653 to measure high-impedance sources. Stray leakage paths can decrease input resistance and increase input currents unless inputs are guarded. Boards must be thoroughly cleaned with TCE or alcohol and blown ...

The 14-pin DIP configuration has been specifically designed to ease input guarding. The pins adjacent to the inputs are not used. Pin Compatibility The ICL7653’s pinout generally corresponds to that of industry-standard 8-pin devices such as the LM741 or LM101. ...
