Abstract
A digital compensation circuit for calibrating a sensor includes a serial communication circuit for receiving data relating to a plurality of parameters and a plurality of registers coupled to the serial communication circuit; one of plurality of registers for reading temperature information. The digital compensation circuit further includes a digital trim circuit for adjusting the temperature information in the one of plurality of registers to a predetermined value at an initial calibration temperature. Finally, the digital compensation circuit further includes means responsive to the digital trim circuit for measuring gain and offset at a predetermined value of the physical parameter being measured.
