典型应用
描述
The LTC1049 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 200μA.
The LTC1049 has a typical offset voltage of 2μV, drift of 0.02μV/°C, 0.1Hz to 10Hz input noise voltage of 3μV P-P 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.
