DescripTion
Low Power Zero-Drift
Operational Amplifier
with Internal Capacitors
The LTC1049 is a high performance, low power zero-drift
operationalamplifier.Thetwosample-and-holdcapacitors
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 200A.
The LTC1049 has a typical offset voltage of 2V, drift of
0.02V/°C, 0.1Hz to 10Hz input noise voltage of 3VP-P
and typical voltage gain of 160dB. The slew rate is 0.8V/s
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.
