GENERAL DESCRIPTION

AM402 is a monolithically integrated current

converter which has been specially developed

for the processing of differential bridge signals.

AM402 is suitable for two- and threewire

applications and has four function blocks.

A high-precision instrumentation amplifier

(IA) serves as an input stage. A reference voltage

source, which can be adjusted to values of

between 4.5 and 10V, excites external components

and a voltage-controlled current output

stage converts the voltage signal. It is thus

possible to generate output currents which correspond

to the normal industrial standards

(0/4–20mA, 12 ± 8mA).
