GENERAL DESCRIPTION
AM411 is a universal voltage amplifier / transmitter IC for signal-conditioning applications. It converts a differential input voltage into an amplified,
single-ended output voltage. Using this IC standardized industrial output voltage ranges (e.g.
0 .. 5, 0 .. 10 V, 1 .. 5 V) can easily be realized.
The IC consists of an instrumentation amplifier
with adjustable offset as input stage and an operational amplifier output stage with adjustable
gain. Offset and gain can be set using external
resistors. A reference voltage source delivering 5
V with a source current up to 10 mA can be used
to power external components (e.g. measurement
bridges, microcontrollers).
The IC is internally protected against reverse polarity and permutation of VCC, VOUT and GND.
Furthermore it is protected against short circuit of
VOUT by an integrated output current limitation.
With its industrial voltage output, protection functions and wide input voltage range AM411 is suitable for a large variety of transducers and sensors.
