Wheatstone bridge single op amp circuit The following schematic shows a Wheatstone bridge single op amp circuit that converts a change in a resistance to a change in differential voltage. The op amp amplifies the difference voltage. This circuit design has a good rejection of common mode noise and ratiometric output (with an ADC using VDD as its reference voltage)
