INA381 amplifier equivalent, current sense amplifier.
*1 Common-mode input range:
–0.2 V to +26 V
* High accuracy amplifier:
– Offset voltage at TA = 25°C
– 500 µV (max.
* Merchant network and server PSU
* Merchant DC/DC
* DC-input BLDC motor drive
* Cordless power tool
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-def.
