    Maximum Offset Voltage Drift: 0.1ВµV/В°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 LTCВ®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 200ВµA.
    The LTC1049 has a typical offset voltage of 2ВµV, drift of
    0.02ВµV/В°C, 0.1Hz to 10Hz input noise voltage of 3ВµVP-P
    and typical voltage gain of 160dB. The slew rate is 0.8V/Вµs
    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 ...

    Chopper vs Bipolar Op Amps—An Unbiased Comparison
    Design Note 42
    George Erdi Table 1 lists the parameters of importance. In all input
    parameters (except noise) the advantage unquestionably goes to the choppers. 5ОјV maximum offset voltage, 0.5ОјV/В°C maximum drift are commonly found
