Abstract
An interface circuit for a bridge sensor has a switch that connects to a resistive bridge circuit. The resistive bridge circuit includes a first input terminal, a second input terminal, and a pair of resistive branches that connect between the first and second input terminals. Both of the resistive branches include an output terminal. The switch is connected to the first input terminal and is in series with both resistive branches for connecting and disconnecting a voltage source from the resistive branch output terminals.
