A method for trimming analog temperature sensors. First, raise a temperature of a temperature sensor to a highest temperature of a qualification temperature range. Then, trim the temperature sensor such that a high temperature code generated by the temperature sensor represents an actual temperature reported by the temperature sensor at the highest temperature. Next, lower the temperature of the temperature sensor to a lowest temperature of the qualification temperature range. Determine a slope error between the high temperature code and a low temperature code generated by the temperature sensor at the lowest temperature. Finally, determine a correction function that compensates for the slope error of measured temperature codes generated by the temperature sensor for temperatures across the qualification temperature range.
