The LTC

operational amplifier. The two sample-and-hold capacitors

usually required externally by other chopper stabilized

amplifiers are integrated on the chip. Further, the LTC1049

offers superior DC and AC performance with a nominal

supply current of only 200

µA.

The LTC1049 has a typical offset voltage of 2

µV, drift of

0.02

and typical voltage gain of 160dB. The slew rate is 0.8V/

µs

with a gain bandwidth product of 0.8MHz.

Overload recovery time from a saturation condition is

6ms, a significant improvement over chopper amplifiers

using external capacitors.

The LTC1049 is available in a standard 8-pin plastic dual

in line, as well as an 8-pin SO package. The LTC1049 can

be a plug-in replacement for most standard op amps with

improved DC performance and substantial power savings.
