    No External Components Required
    Maximum Offset Voltage: 10µV
    Maximum Offset Voltage Drift: 0.1µV/°C
    Single Supply Operation: 4.75V to 16V
    Input Common Mode Range Includes Ground
    Output Swings to Ground
    Typical Overload Recovery Time: 6ms
    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

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 200A. The LTC1049 has a typical offset voltage of 2V, drift of 0.02V/C, 0.1Hz to 10Hz input noise voltage of 3VP-P and typical voltage gain of 160dB. The slew rate is 0.8V/s 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.
