Another common configuration to “excite” a sensor
(such as a strain gauge, pressure sensor or thermistor)
is
wheatstone bridge provides a differential output
instead of a single-ended output.
a wheatstone bridge utilizing one to three digital
potentiometers. The digital potentiometers in this
example are used to trim the offset and gain of the
wheatstone bridge.
