General Description'
The Maxim ICL7652 is a chopper-stabilized amplifier,
ideal for applications requiring low-level signal ampli-
fication and conditioning. This device offers distinct
performance advantages over the ICL7650, including
improved noise performance and a wider common-
mode input voltage range. The bandwidth and slew
rate are slightly reduced.
The ICL7652 virtually eliminates the Vos error term in
system errorcalculations, eliminating the reliability and
cost problems associated with potentiometer adjust-
ments. In addition, the 0.01pV/° C Vos drift specification
and the excellent long term offset stability eliminate the
need for periodic Vos trimming.
The offset nulling circuit for the 8-lead ICL7652 is con-
trolled by an internal oscillatorcircuit. The 14-lead version
offers the capability of connecting an external oscillator
to control the Vos nulling operation. The 14-Iead
device has an output voltage clamp circuit to minimize
overload recovery time.
Applica tions
The ICL7652 is ideal for all preamplifier circuit appli-
cations where low offset voltage is critical and periodic
adjustment of the offset is difficult or inaccessible.
