AM400 - Universal Amplifier and Voltage-to-Current Converter IC

Package variants of the V/I-converter and voltage amplifier IC AM400
AM400 is an universal amplifier IC for sensing and signal-conditioning applications. It is suitable for differential or single-ended input voltages and generates both a voltage and a current output signal. Its modular design, integrated voltage and current source and protection functions allow a wide range of industrial applications.

Applications

  • Sensor signal-conditioner
  • Current-loop transmitter
  • Front and back end IC for µC
  • Protected analog output stage
  • Impedance converter
  • Industrial network driver
