The INA183 is a high-precision voltage-output, current-shunt monitor (also called current-sense amplifier) commonly used for overcurrent protection, precision-current measurement for system optimization, or in closed-loop feedback circuits. This device can sense drops across shunt resistors at common-mode voltages from 2.7 V to 26 V. 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.
This device operates by drawing power from the IN+ pin drawing a maximum of 130 µA of supply current. All versions are specified from –40 °C to 125 °C and are offered in the 5-pin SOT-23 package.
