1. 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.
2. 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.
