SAR ADC or Delta Sigma ADC? What's Your Preference?

Successive approximation register (SAR) analog to digital converters (ADCs) take a continuous analog waveform and converts it into a discrete digital representation via a binary search through all possible quantization levels before converging upon a digital output.

 

Conversely, Delta-Sigma ADCs employ different configurations of complicated digital filtering to enhance the overall resolution of the ADC.

 

SAR and Delta-Sigma are two of the most common types of precision analog-to-digital converters (ADCs) available today.
