Texas Instruments INAx191 Current Sense Amplifier is a low-power, voltage-output, current-shunt monitor (also called a current-sense amplifier). This amplifier is commonly used for overcurrent protection, precision-current measurement for system optimization, or closed-loop feedback circuits. It can sense drops across shunts at common-mode voltages from -0.2V to +40V, independent of the supply voltage. The low input bias current of the INAx191 permits the use of larger current-sense resistors, and thus provides accurate current measurements in the µA range. Five fixed gains are available: 25V/V, 50V/V, 100V/V, 200V/V, or 500V/V. The low offset voltage of the zero-drift architecture extends the dynamic range of the current measurement. This also allows for smaller sense resistors with lower power loss while still providing accurate current measurements.
