3 Description
The INA199 series of voltage-output, current-shunt monitors (also called current-sense amplifiers) are commonly used for overcurrent protection, precision- current measurement for system optimization, or in closed-loop feedback circuits. This series of devices can sense drops across shunt resistors at common- mode 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.
