Abstract
A sensor arrangement, particularly suitable for pressure sensors is disclosed, in which differential output signals from a pressure sensor are switched between two amplifiers and fed to a microcomputer where they are stored as two pairs of signals in digital form. The two pairs of signals are combined to cancel amplifier offset voltages.
