Claim 6:
7. The ADC of claim 1, wherein the calibration circuitry includes a third calibration circuitry input and threshold proximity detect circuitry having a first threshold proximity detect circuitry input, a second threshold proximity detect circuitry input and a threshold proximity detect circuitry output, the first threshold proximity detect circuitry input coupled to the first calibration circuitry input, the second threshold proximity detect circuitry input coupled to the third calibration circuitry input, and threshold proximity detect circuitry configured to:
receive the analog signal at the second threshold proximity detect circuitry input;
receive the comparison results at the second threshold proximity detect circuitry input;
determine if the analog signal is proximate to one of the respective reference thresholds based on the analog signal and the comparison results; and
provide an enable signal at the threshold proximity detect circuitry output in response to determining that the analog signal is proximate to one of the respective reference thresholds.
