LTC1049

The LTC®1049 is a high performance, low power zero-drift 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 200A.

The LTC1049 has a typical offset voltage of 2V, drift of 0.02V/°C, 0.1Hz to 10Hz input noise voltage of 3V_P-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.
