Abstract
A circuit includes a multiplexer, an analog-to-digital converter, and a processor that compares a sequence of digital outputs from the analog-to-digital converter to a sequence of normal ranges that correspond with the digital outputs in order to provide an error output when one of the digital outputs is outside its normal range.
