INA190 Datasheet (Texas Instruments) - Precision Current-Sense Amplifier

INA190, Precision Current-Sense Amplifier

The INA190 is a low-power, voltage-output, currentshunt 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 co
