    摘要: An arrangement monitors the values at sensors such as temperature sensors which each generate a voltage value related to the particular sensor temperature. The arrangement produces a digital value representative of the temperature at each sensor, wherein errors caused by fluctuations in the temperature of the arrangement circuitry and aging are reduced toward zero. The arrangement corrects for errors for a wide range of combinations of sensor temperatures and temperature fluctuation in the circuitry of the arrangement. The arrangement includes separate channel circuitry associated with each sensor and temperature independent references associated with each sensor type. Generally, to provide error correction, the arrangement uses stored comparison values to correct for channel-to-channel circuitry differences and stored values associated with the independent references to correct for temperature fluctuation and aging of the arrangement.
