ABSTRACT:
A multi-channel analog to digital converter which facilitates calibration of the analog to digital converter and respective input channels to the analog to digital converter, and a method for calibrating the analog to digital converter. A multi-channel ADC (1) comprising an ADC circuit (2) for converting analog signals received on input channels CH1to CHN to digital output signals comprises a primary offset storing register (24) and a primary gain storing register (25) for storing respective primary offset and gain correction codes which are applied to the digital output signals in a primary correcting circuit (14) for correcting for the offset and gain errors introduced by the ADC circuit (2). A plurality of secondary offset storing registers (33) and a plurality of secondary gain storing registers (34) store respective secondary offset and gain correction codes which are applied to the digital output signals in a secondary correcting circuit (18) for correcting for offset and gain errors introduced by corresponding ones of the input channels CH1to CHN.
