Abstract
An integrated circuit includes a successive approximation register (SAR) analog-to-digital converter (ADC). The ADC includes a bit step selector. During testing of the ADC, the bit step selector selects a number of bits to be tested for a next analog test voltage based on digital values that are within an integer delta value of most recent digital value for a most recent analog test voltage.
