RENESAS ICL7650SCBA-1Z Operational Amplifier, 2 MHz, 2.5 V/µs, 4.5V to 16V, SOIC, 8 Pins

ICL7650SCBA-1Z is an ICL7650S super chopper-stabilized amplifier in a 8 pin SOIC package. It offers exceptionally low input offset voltage and is extremely stable with respect to time and temperature. It is a direct replacement for the industry-standard ICL7650 offering improved input offset voltage, lower input offset voltage temperature coefficient, reduced input bias current, and wider common mode voltage range. Intersil�s unique CMOS chopper-stabilized amplifier circuitry is user-transparent, virtually eliminating the traditional chopper amplifier problems of intermodulation effects, chopping spikes, and overrange lockup. The chopper amplifier achieves its low offset by comparing the inverting and non-inverting input voltages in a nulling amplifier, nulled by alternate clock phases. Two external capacitors are required to store the correcting potentials on the two amplifier nulling inputs; these are the only external components necessary.
