INA381A4IDSGT General Description

The INA381A4IDSGT is a versatile product that combines a current-sensing amplifier and a high-speed comparator in one convenient device. This allows for the detection of overcurrent conditions by measuring the voltage across a current-shunt resistor and comparing it to a user-defined threshold limit. The current-shunt monitor can handle differential voltage signals on common-mode voltages ranging from -0.2 V to 26 V, regardless of the supply voltage

Key Features

Precision temperature sensor
Advanced noise reduction techniques
High-speed data acquisition systems
