GENERAL DESCRIPTION
The TC7652 is a lower noise version of the TC7650,
sacrificing some input specifications (bias current and band-
width) 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 problems from exter-
nal trim components. Like the TC7650, the TC7652 re-
quires only two noncritical external caps for storing the
chopped null potentials. There are no significant chopping
spikes, internal effects or overrange lockup problems.
