    over a wide supply range of 4.75V to 36V or 4.75V to
    60V for the LTC2057HV. Offset voltage and 1/f noise are
    suppressed, allowing this amplifier to achieve a maximum
    offset voltage of 4μV and a DC to 10Hz input noise voltage of 200nVP-P (typ). The LTC2057’s self-calibrating ...

    Buffered ADC Family Eliminates
    Signal Conditioning Complexity
    Joe Sousa, Andrew Thomas, Clement Wagner, Mark Thoren
    Engineers often assume that analog-to-digital converter
    inputs are high impedance. Direct-sampling SAR ADC
    inputs will often be high impedance when not converting, but will draw “spikes” of current at the beginning
    of sample acquisition. On average, this behavior can be
    modeled as a crude nonlinear resistance that is inversely
    proportional to the sample capacitor size and sample rate,
    but instantaneously the signal chain must be able to settle
    completely in response to this abuse before acquisition
    ends and a conversion begins. Coupling a signal chain to an ADC is an art form, often requiring a combination of theory
    and experimentation. By contrast, the LTC2358 family of
    multi-channel, buffered high voltage SAR ADCs offers
    truly high impedance inputs that simplify or eliminate the
    need for signal conditioning in many cases. When signal
    conditioning is required, it can be directly connected to
    the LTC2358 inputs without regard to its ability to drive
    a switched capacitor. The following circuits show some
    applications that take advantage of the properties of the
    LTC2358 inputs. ...
