Abstract
An analog-to-digital converter includes an input terminal, a digital-to-analog converter, a comparator, and successive approximation circuitry. The input terminal is configured to receive a multi-bit digital threshold value from circuitry external to the analog-to-digital converter. The successive approximation circuitry is coupled to the comparator and the digital-to-analog converter. The successive approximation circuitry is configured to operate in a comparison mode and a conversion mode, and to provide the multi-bit digital threshold value to the digital-to-analog converter while operating in the comparison mode. The comparator is coupled to the digital-to-analog converter and the successive approximation circuitry. The comparator is configured to output a signal that indicates whether an analog input signal exceeds an analog threshold signal corresponding to the multi-bit digital threshold value.
