Clamp Circuit for Fast Overload Recovery

General Description

The TC7652 is a lower noise version of the TC7650,

sacrificing some input specifications (bias current and

bandwidth) to achieve a 10x reduction in noise. All the

other benefits of the chopper technique are present,

(i.e, freedom from offset adjust, drift and reliability prob-

lems from external trim components). Like the TC7650,

the TC7652 requires only two noncritical external caps

for storing the chopped null potentials. There are no

significant chopping spikes, internal effects or over-

range lockup problems.
