More Information
The INAx191 is a low-power, voltage-output, current-shunt monitor (also called a current-sense amplifier) that is commonly used for overcurrent protection, precision-current measurement for system optimization, or in closed-loop feedback circuits. This device can sense drops across shunts at common-mode voltages from –0.2 V to +40 V, 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: 25 V/V, 50 V/V, 100 V/V, 200 V/V, or 500 V/V. The low offset voltage of the zero-drift architecture extends the dynamic range of the current measurement, and allows for smaller sense resistors with lower power loss while still providing accurate current measurements.
