INA185/INA185-Q1 Current Sense Amplifier

Texas Instruments INA185/INA185-Q1 Current Sense Amplifier is designed for cost-sensitive space-constrained applications. This device is a bidirectional, current-sense amplifier (also called a current-shunt monitor). The INA185/INA185-Q1 senses the voltage drop across a current-sense resistor at common-mode voltages from –0.2V to +26V, independent of the supply voltage. The INA185/INA185-Q1 integrates a matched resistor gain network in four fixed-gain device options: 20V/V, 50V/V, 100V/V, or 200V/V. This feature, matched gain resistor network, minimizes gain error and reduces the temperature drift.
