INA149 datasheet

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 INA149 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

1. High-Voltage Current Sensing

2. Battery Cell Voltage Monitoring

3. Power-Supply Current Monitoring

4. Motor Controls

5. Replacement for Isolation Circuits
