AM422-2 is a voltage-to-current converter IC with integrated protection functions especially suitable for industrial sensing and signal-conditioning in current-loop applications. It converts a single-ended input voltage into a current output signal (e.g. 4 .. 20 mA) with adjustable offset and full-scale current.
