    INA199A3DCKR

    The INA199 series of voltage-output, current-shunt
    monitors (also called current-sense amplifiers) are
    commonly used for overcurrent protection, precisioncurrent measurement for system optimization, or in
    closed-loop feedback circuits. This series of devices
    can sense drops across shunt resistors at commonmode voltages from –0.3 V to 26 V, independent of
    the supply voltage. Three fixed gains are available:
    50 V/V, 100 V/V, and 200 V/V. The low offset of the
    zero-drift architecture enables current sensing with
    maximum drops across the shunt as low as 10-mV
    full-scale.
    These devices operate from a single 2.7-V to 26-
    V power supply, drawing a maximum of 100 µA
    of supply current. All versions are specified from –
    40°C to 125°C, and offered in both SC70-6 and thin
    UQFN-10 packages.
