The ICL7650S Super Chopper-Stabilized Amplifier 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. All improvements are highlighted in bold italics in the Electrical Characteristics section. Critical parameters are guaranteed over the
entire commercial temperature 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,...
