Intersil ICL7650CPD Vintage Chopper Stabilized Precision Op Amp DIP14
Full Description & History
Original Intersil ICL7650CPD precision CMOS chopper-stabilized operational amplifier in a 14-pin through-hole DIP package. Designed for low-offset, low-drift analog signal amplification in measurement, instrumentation, sensor-interface, and control circuits. Features approximately 2 MHz gain-bandwidth product and operates over a 4.5V to 16V total supply range.
LIFECYCLE: OBSOLETE
HISTORICAL BACKGROUND:
The ICL7650 family was developed for precision analog applications where conventional operational-amplifier offset voltage and temperature drift could introduce measurement errors. Its chopper-stabilized architecture uses automatic offset correction to maintain accuracy over time and changing operating conditions. Devices in this family were used in instrumentation, thermocouple and thermistor measurement circuits, strain-gauge amplifiers, and industrial electronic controls. This example carries an early 1980s production marking.
