AM402 - Voltage-to-Current Converter IC

Package variants of the V/I-converter IC AM402
AM402 is a voltage-to-current converter IC with integrated protection functions and voltage source. It converts a differential input voltage into a current output signal with adjustable offset and gain. AM402 is particularly suitable for industrial sensing and signal-conditioning in two- or three-wire applications.
