INA381 Datasheet (Texas Instruments) - Current Sense Amplifier

INA381, Current Sense Amplifier

The INA381 includes both a 26-V common-mode, current-sensing amplifier and a high-speed comparator.

This device detects overcurrent conditions by measuring the voltage developed across a current-shunt resistor and comparing that voltage to a user-defined threshold limit set by the comparator referen
