AM452 is an integrated transducer with an adjustable current output which has been specifically designed for the conditioning of differential input signals. It permits the independent adjustment of the offset and fullscale current using just a few components. The IC consists of various functional modules. In addition to the instrumentation amplifier in the signal path there is an operational amplifier which is used to set the gain. The offset can be adjusted using the Zero adjust stage and/or the SET stage module. An additional operational amplifier can supply external components. The adjustable current output stage permits 2- and 3-wire operation by way of a simple amendment to the circuitry. The IC is distinguished by its many protective functions which include protection against reverse polarity and short-circuiting and also an internal current limit.
