ABSTRACT:
A circuit for converting input analog signals to output digital signals including an analog-to-digital converter having an analog input, an offset input and a digital output that represents the value of a signal at the analog input offset by an amount related to the value of the signal at the offset input, signal conditioning circuitry for receiving the input analog signal and providing it to the analog input via one of a plurality of different paths or under one of a plurality of different conditions, the different paths or different conditions providing different offsets to the input analog signal, and an offset correction memory storing offset correction characteristics for respective paths or conditions and being connected to provide an offset signal based on the characteristic for a path or condition to the offset input.
