    GENERAL DESCRIPTION
    The AD8202 is a single-supply difference amplifier for amplifying
    and low-pass filtering small differential voltages in the presence of a
    large common-mode voltage (CMV). The input CMV range
    extends from 6 V to +28 V at a typical supply voltage of 5 V.
    The AD8202 is available in die and packaged form. The MSOP
    and SOIC packages are specified over a wide temperature range,
    from 40°C to +125°C, making the AD8202 well-suited for use
    in many automotive platforms.
    Automotive platforms demand precision components for
    better system control. The AD8202 provides excellent ac and
    dc performance keeping errors to a minimum in the user’s
    system. Typical offset and gain drift in the SOIC package are
    0.3 V/°C and 1 ppm/°C, respectively. Typical offset and gain
    drift in the MSOP package are 2 V/°C and 1 ppm/°C, respec-
    tively. The device also delivers a minimum CMRR of 80 dB
    from dc to 10 kHz.
    The AD8202 features an externally accessible 100 k resistor
    at the output of the Preamp A1 that can be used for low-pass
    filter applications and for establishing gains other than 20.
