GENERAL DESCRIPTION

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. 0/4–20mA) signals to be produced

relatively easily.
