The LTC1047 is a micropower, high performance dual zero-drift operational amplifier. The sample-and-hold capacitors usually required by other chopper amplifiers are integrated on-chip, minimizing the need for external components. The LTC1047 has a typical offset voltage of 3µV, drift of 10nV/°C, input noise voltage typically 3.5µVP-P, and typical voltage gain of 150dB. The common mode rejection is 110dB minimum, with minimum power supply rejection of 105dB. The LTC1047 also offers a 0.2V/µs slew rate and a gain bandwidth product of 200kHz. Overload recovery time from saturation is 70ms, four times faster than chopper amplifiers with external capacitors. The LTC1047 is available in a standard plastic 8-pin PDIP as well as a 16-pin SW package. The LTC1047 is a plug-in replacement for most dual op amps with improved DC performance and substantial power savings.
