Industrial Voltage-to-Current Converter IC

AM462 is an industrial voltage-to-current converter IC. It converts a single-ended input voltage into a current output signal with adjustable offset and gain. With its protection functions and integrated voltage and current source it is suitable for industrial sensing and signal-conditioning in current-loop or three-wire applications.
