AM422-1 - Voltage-to-Current Converter IC for 3-Wire Operation

AM422-1 is a compact voltage-to-current converter IC for 3-wire operation with integrated protection functions and voltage source. It converts a single-ended input voltage into a current output signal with adjustable offset and gain. The IC is especially suitable for price sensitive industrial applications with single-ended input signals.

Applications

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