A quasi-Wheatstone bridge linear output circuit with one op amp
by Crutschow, Electro-Tech-Online community member A Wheatstone bridge is sometimes used to convert a variable resistance, such as a thermistor or strain-gage, to a voltage with zero volts out at some particular resistance (such as at 0°C for the thermistor). A bridge circuit has the advantage of being able to generate a 0V null output […]
