    Available in 8-Pin SO and PDIP Packages 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 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. Applications n n n n Overload recovery time from a saturation condition is
    6ms, a significant improvement over chopper amplifiers ...
