GENERAL DESCRIPTION
The AM411 is a monolithic voltage transmitter,
designed for flexible bridge input signal condi-
tioning. The integrated circuit is ideally suited
for a wide variety of transducers with an differ-
ential output signal. It contains a high accuracy
instrumentation amplifier for differential input
signals, an operational amplifier output stage,
and a 5V reference. Output range and gain are
adjustable by external resistors. Using the inter-
nal instrumentation amplifier the AM411 is a
standard sensor transmitter with the possibility
to indicate an over range signal. With the inter-
nal connected operational amplifier input this
IC can be used as an adjustable voltage–to–
voltage transmitter.
