ANALOG-TO-DIGITAL CONVERTER WITH RANGE ERROR DETECTION

摘要

A circuit (200) includes a multiplexer (204), an analog-to-digital converter (208), and a processor (216) that compares a sequence (DM) of digital outputs from the analog-to-digital converter to a sequence (217) of normal ranges that correspond with the digital outputs in order to provide an error output (219) when one of the digital outputs is outside its normal range.
