UNIVERSAL TEMPERATURE COMPENSATION APPLICATION SPECIFIC INTEGRATED CIRCUIT

摘要

A universal temperature compensation circuit for use with a temperature sensor operative to generate an analog temperature signal based on the temperature thereof. The universal temperature compensation circuit comprises an analog to digital converter (18) in electrical communication with the temperature sensor. The analog to digital converter is operative to generate a digital temperature signal from the analog temperature signal. In electrical communication with the analog to digital converter is an electronic storage device containing digital data correlated to temperatures of the temperature sensor. The universal temperature compensation circuit further includes a digital to analog converter (64) in electrical communication with the electronic storage device. The digital to analog converter is operative to generate an electronic storage device. An amplifier (48) is in electrical communication with the digital to analog converter and is operative to buffer and generate a final output voltage level (56,58) from the analog voltage level. The final output voltage level being correlated to the temperature of the temperature sensor.
