LTC1049CS8#PBF

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 200µA. Overload recovery time from a saturation condition is 6ms, a significant improvement over chopper amplifiers using external capacitors. This can be a plug-in replacement for most standard op amps with improved DC performance and substantial power savings. Typical applications are 4mA to 20mA current loops, thermocouple amplifiers, electronic scales, medical instrumentation, strain gauge amplifiers, high resolution data acquisition.
