Successive-approximation ADC

A Successive-Approximation Analog-to-Digital Converter (SAR ADC) is a type of ADC that converts an analog signal into a digital signal through a process of successive approximation. It is widely used in applications requiring moderate speed and high resolution. The SAR ADC typically consists of a sample-and-hold circuit, a comparator, and a binary search algorithm implemented with a digital-to-analog converter (DAC).
