Chopper Stabilized Operatlonal Amplifier
19-3031; Rev tt 1988
General Minion
The Maxim ICL7652 Is a chopper-stabillzed amplifier,
Ideal for applications requlri Iow-ievel signal ampli-
flttatlort and conditioning. Th device otters distinct
performance advantages over the ICL7650, including
improved noise performance and a wider common-
mode Input voltage range. The bandwidth and slow
rate are ellghtty reduced.
The ICL7652 virtually eliminates the Vos error term in
system ttrrorealeulatlons, eliminating the reliability and
cost problems associated with otentiometer adjust-
ments. In addition, the 0.01 pV/° C osdrift specification
and the excellent long term offset stability eliminate the
need for ptsrlodlto Vos trimming.
The offset nulling clrcuit tor the 8-Iead iCL7652 is con-
trolled by an Intemaloeclllatorclrcuit.1he14-iead version
offers the capability of connectl ng an external oscillator
to control the Vos nulling operation. The 14-Ieed
device has an output voltage clamp circuit to minimize
overload recovery time.
Applications
The ICL7652 ls Ideal tor all preamplifier circuit appli-
cations where low offset voltage is critical and periodic
adjustment of the offset is difficult or inaccesslbie.
