Industrial Converter and Protector IC

AM460

FEATURES

GENERAL DESCRIPTION

AM460 is a universal converter and amplifier IC

with a number of additional functions. The IC basi-

cally consists of an amplifier, whose gain can be set

externally, and parallel output stages which can con-

dition 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.

• Supply voltage: 6...35V

• Wide working temperature range:

–40°C...+85°C

• Adjustable integrated reference voltage

source: 4.5 to 10V

• Additional voltage/current source

• Operational amplifier with integrated

driver stage

• Adjustable amplification

• Analogue parallel voltage (0...5/10V) and

current output (0/4...20mA)

• Protection against reverse polarity and

short-circuiting

• Output current limit

• Low-cost device: replaces a number of

discrete elements

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 cur-

rent loop (e.g. 0/4–20mA) signals to be produced

relatively easily.

• 2- and 3-wire operation
