An apparatus includes a sample holding circuit, a comparator, a digital-to-analog converter, a clock generator, a successive approximation logic circuit, and a background calibration circuit. The apparatus converts an analog signal into digital data based on an asynchronous clock signal. The clock signal follows the number of clocks in a converting operation section through a background calibration scheme.
