High-Voltage Difference Amplifier

The INA146 is an integrated precision difference amplifier in an SO-8 style package. It can operate with a common mode input voltage in excess of the supply voltage to the IC. With a single sided +5 V supply this IC can handle common mode input voltages up to +40 V or ±100 V with a symmetrical ±15 V supply. The IC is ideally suited for use in applications such as high precision current shunt measuring in high voltage test equipment, as a sensor amplifier, as a monitoring device for powered vehicles or as a voltage controlled current source.
