2MHz, Super Chopper-Stabilized

Operational Amplifier

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, 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.

The clock oscillator and all the other control circuitry is

entirely self-contained. However the 14 lead version includes

a provision for the use of an external clock, if required for a

particular application. In addition, the ICL7650S is internally

compensated for unity-gain operation.

*Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are

MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
