A digital piezoresistive pressure transducer is provided wherein a pressure differential causes the resistance of two equal, diffused piezoresistances to change by equal but opposite amounts. The variable resistance of the two piezoresistance elements is utilized to correspondingly vary the time duration of two distinct voltage levels. The ratio of the time duration of the two voltage levels bears a linear relationship to the differential pressure across the transducer that enables the various values of pressure to be determined.
