AM422-2 - Voltage-to-Current Converter IC (Current-Loop Appl.)

Package variants of the V/I-converter IC AM422-2
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.

Applications

  • Sensor signal-conditioner
  • Current-loop transmitter
  • Protected V/I-converter IC
  • Analog back end for µC
  • Voltage driven current source
  • Industrial process control
