AM460 is a universal converter and amplifier IC with a number of additional functions.  The IC basically consists of an amplifier, whose gain can be set externally, and parallel output stages which can condition signals referenced to ground in industrial voltage and current signals.  An additional reference voltage source for the supply of external components is also included in the device.  A further operational amplifier can be connected up as a current source, voltage reference or comparator.

One of the main features of the IC is its integrated protective circuitry.  The device is protected against reverse polarity, short-circuiting and has a built in output current limit.  Amplifier IC AM460 enables industrial standard voltage (e.g. 0-5/10V) and current loop (e.g. 4-20 mA) signals to be produced relatively easily.
