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.
