LTC1049 Datasheet PDF

●The LTC1049CN8#PBF is a high performance low power zero-drift Operational Amplifier for use with electronic scales. The two sample-and-hold capacitors usually required externally by other chopper stabilized amplifier 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 3µVP-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.
