AM452 - Voltage-to-Current Converter IC

Package variants of the V/I-converter IC AM452
AM452 is a voltage-to-current converter IC with integrated protection functions suitable for sensing applications with current driven Wheatstone bridges. It converts a differential input voltage into an adjustable current output signal. The IC is suitable for two- and three-wire operation and compatible with HART-modems.
