AM402 - Voltage-to-Current Converter IC

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.

Applications

  • Sensor signal-conditioner
  • Current-loop transmitter
  • Industrial current output driver
  • Protected V/I-converter
  • Factory automation
  • Industrial process control
