AM400 Universal Amplifier and Voltage-to-Current Converter IC

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.

AM400 is a monolithically integrated measuring amplifier with a parallel current and voltage output which has been specifically developed for the processing of differential input signals. AM400 consists of various functional modules. It contains both an instrumentation amplifier input and an input for signals referenced to ground. One particular feature of the device is the current and voltage outputs which can be used simultaneously. The output ranges can be selected using external resistors, enabling AM400 to be configured for the analog 0/4...20mA and 0...5/10V industrial power network, for example. Integrated voltage and current sources covering a wide range of values can be used to power external components.
