The noise reduction, however, is greater compared to the SAR. Delta-sigma-ADC technology has caught up to that of SAR (successive-approximation-register) ADCs in sampling frequency. A crossover in the sampling-time regions of approximately 100 kHz to 1 MHz exists in both types of devices. These two types of converters also match in most key specifications. Delta Sigma ADC converter. 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.

SAR-based 2018-09-21 Basic block diagram of SAR-ADC architecture [10] Figure 3 clearly shows that for an SNDR below 68 dB or an 11-bit ENOB, the architecture that has a lower power consumption feature is the SAR-ADC. Above 68 dB, we seldom see an SAR-ADC solution, but delta-sigma ADCs have superior performance.

Flash vs. Sigma-Delta ADCs Flash ADCs do not compete with a sigma-delta architecture because currently the achievable conversion rates differ by up to two orders of magnitude. The sigma-delta architecture is suitable for applications with much lower bandwidth, typically less than 1MHz, and with resolutions in the 12- to 24-bit range.
