Abstract

A testing circuit configures an analog to digital converter (ADC) to receive a test signal instead of a live input signal. The testing circuit compares an output test value from the ADC to an expected test value for the test signal. The testing circuit provides an expected live output value to a digital circuit instead of the output test value, thereby preventing the ADC from providing a value to the digital circuit not based on the live input signal.
