Abstract: Examples herein relate to electronic devices that include an asynchronous successive approximation register (SAR) analog-to-digital converter (ADC) that implements timing adjustment based on output statistics. In an example, an electronic device includes an asynchronous SAR ADC, a statistics monitor, and an operation setting circuit. The asynchronous SAR ADC is configured to output output data. The statistics monitor is configured to capture samples at a bit position of the output data. The statistics monitor is further configured to generate an operational setting based on the captured samples. The operation setting circuit is configured to adjust an operating condition of the asynchronous SAR ADC based on the operational setting.
