Abstract: A low power measurement circuit for a position sensor incorporating strain gauges. The position sensor includes a bridge resistive network coupled to a multiplexer. The multiplexer routes current through different portions of the position sensor creating different resistive networks sensitive to forces applied to the position sensor. Current flowing through the resistive networks generate output signals proportional to the forces applied to the position sensor. A sample and hold circuit allows the position sensor to be de-energized while an analog to digital converter digitizes the output signals. A programmable controller and a digital to analog converter are included to create a flexible amplifier stage. The circuit further includes a controller for controlling the operation of the multiplexer, programmable amplifier, digital to analog converter, and analog to digital converter.
