Description

The INA149 is a precision unity-gain difference amplifier with a very high input common-mode voltage range. It is a single, monolithic device that consists of a precision op amp and an integrated thin film resistor network.

The device can accurately measure small differential voltages in the presence of common-mode signals up to ±275 V. The INA149 inputs are protected from momentary common-mode
or differential overloads of up to 500 V.

Applications :

• High-Voltage Current Sensing

• Battery Cell Voltage Monitoring

• Power-Supply Current Monitoring

• Motor Controls

• Replacement for Isolation Circuits
