AM452

 

  Voltage-to-Current Converter IC

 

AM452 is a voltage-to-current converter IC with integrated protection functions suitable for sensing applications with current driven Wheatstone bridges. It converts a differential input voltage into an adjustable current output signal. The IC is suitable for two- and three-wire operation and compatible with HART-modems.

 

Applications

 

  • 1.Sensor signal-conditioner
  • 2.Current-loop transmitter
  • 3.Protected V/I-converter
  • 4.Compatible with HART-modems
  • 5.Industrial network driver
  • 6.Industrial process control
