Abstract
An electronically calibrated sensor (100) includes a sensing element (102) with an output coupled to a signal conditioning circuit (104). The signal conditioning circuit (104) is adapted to be highly computationally efficient and operable for compensating for temperature and part-to-part variation on the sensing element output for providing a useable sensor output signal. The signal conditioning circuit (104) includes an analog-to-digital/digital-to-analog (ADC/DAC) conversion device (112). The ADC/DAC (112) is operable to perform both analog input signal analog-to-digital conversion and digital output signal digital-to-analog conversion. The ADC/DAC (112) is further adapted to provide analog control signals to input signal conditioning circuits (104, 106).
