As the name implies, the SAR ADC basically implements a binary search algorithm. Therefore, while the internal circuitry may be running at several megahertz (MHz), the ADC sample rate is a fraction of that number due to the successive-approximation algorithm.

For each bit, the SAR logic outputs a binary code to the DAC that is dependent on the current bit under scrutiny and the previous bits already approximated. The comparator is used to determine the state of the current bit. Frank Ohnhäuser, Theory and realization of high-end analog-to-digital converters (ADC) based on the principle of successive approximation (SAR), PhD Thesis at the University of Erlangen-Nürnberg, Erlangen, 2008. A major disadvantage of SAR ADC is its design complexity and cost of production. Applications of SAR ADC As this is a most commonly used ADC, it's used for many applications like uses in biomedical devices that can be implanted in the patient, these types of ADCs are used because it consumes very less power.

The delta sigma converter (ΔΣ-converter or ΣΔ-converter) is one of the most used methods for high-resolution analog to digital converters (ADC) at a certain speed. Nowadays it is often included in the microcontrollers displacing the typical SAR standard converter. register (SAR) ADC exhibits signiﬁcantly high energy efﬁciency compared to other prevalent ADC architectures due to its good tradeoffs among power consumption, conversion accuracy, and design complexity.

SAR operation (4-bit ADC example) Notice that four comparison periods are required for a 4-bit ADC. Generally speaking, an N-bit SAR ADC will require N comparison periods and will not be ready for the next conversion until the current one is complete.

The SAR ADC is the commonly used architecture for data acquisition systems that are widely employed in medical imaging, industrial process control, and optical communication systems. In these applications, we usually need to digitize the data generated by a large number of sensors. SAR ADC Conﬁguration: An SAR ADC is composed of a sample hold circuit, a comparator, a DAC, SAR logic circuit and timing generator (Fig.1).
