LTC1050

Precision Zero-Drift

Operational Amplifier

with Internal Capacitors

FEATURES

DESCRIPTIO

The LTC^®1050 is a high performance, low cost zero-drift

operational amplifier. The unique achievement of the

LTC1050 is that it integrates on-chip the two sample-and-

hold capacitors usually required externally by other chop-

per amplifiers. Further, the LTC1050 offers better com-

bined overall DC and AC performance than is available

from other chopper stabilized amplifiers with or without

internal sample-and-hold capacitors.
