EXAMPLE APPLICATIONS

• Interface IC for sensing elements in a resistor bridge circuit (e.g. piezoresistive pressure sensing

elements) with electronic compensation of errors via an external microcontroller. In this

application AM417 is used as a preamplifier to set the operating point.

• Signal conditioning IC with an external, analog compensation network, in which the offset can

be adjusted using additional resistors on the sensing element and the gain using AM417.

How to protect the output of the AM467 against reverse polarity see [3]
