Description
The INA190 is a low-power, voltage-output, current-shunt monitor
(also called a current-sense amplifier). This device is commonly
used for overcurrent protection, precision current measurement for
system optimization, or in closed-loop feedback circuits. The
INA190 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 device permits the use of larger current-sense resistors, thus providing accurate current measurements in the microamp range. The low offset voltage of the zero-drift architecture extends the dynamic range of the current measurement. This feature allows for smaller sense resistors with lower power loss, while still providing accurate current measurements.
