Zero-Drift Operational Amplifier

DESCRIPTIO
The LTC
dual zero-drift operational amplifier. The sample-and-hold
capacitors usually required by other chopper amplifiers
are integrated on-chip, minimizing the need for external
components.
The LTC1047 has a typical offset voltage of 3µV, drift
of 10nV/°C, input noise voltage typically 3.5µV
and typical voltage gain of 150dB. The common mode
rejection is 110dB minimum, with minimum power supply
rejection of 105dB. The LTC1047 also offers a 0.2V/µs
slew rate and a gain bandwidth product of 200kHz. Over-
load recovery time from saturation is 70ms, four times
faster than chopper amplifiers with external capacitors.
The LTC1047 is available in a standard plastic 8-pin PDIP
as well as a 16-pin SW package. The LTC1047 is a plug-in
replacement for most dual op amps with improved DC
performance and substantial power savings.
