Sigma-Delta Conversion Method. The Sigma-Delta ADC operates in a completely different manner. Instead of taking discrete samples of the analog signal, the input is converted into a continuous process. The difference between the input and a 1-bit DAC is fed into an integrator.

The benefit of delta-sigma ADCs: * high resolution * low DNL * cheap * due to oversampling: very simple antialiasing filters Mind: you need a continous, fixed, low jitter sampling rate Read the datasheets carefully. For more detailed informations you need to provide more detailed requirements. Klaus

It has a very different architecture from the other two types. At its core is a 1-bit ADC. Key Differences between SAR and Delta-Sigma ADC Both ADCs enjoys a maximum sampling rate of 10 Msamples/s. The delta-sigma’s net output data word rate is lower than the sampling rate by the decimation factor and is usually in the ksamples/s range. The noise reduction, however, is greater compared to the SAR. A key difference between the SAR and Delta-Sigma topology is in how the sampling of the input signals relate to the data conversion result. The SAR converter takes a sample, or a snapshot, of the input and captures the signal level at a specific point in time and performs a conversion. In comparison, the Δ-Σ ADC typically has a fixed power draw. An example of high throughput together with power scaling can be found in ADI's 5MSPS 18-Bit AD7960 SAR ADC. Oversampling with a SAR ADC can improve anti-aliasing and reduce noise.

Golden Gloves ADC Championship Match – SAR vs. Sigma-Delta (Σ∆) By Andrew Siska, Senior Applications Engineer, and Meng He, Senior Product Marketing Engineer, Cypress Semiconductor Corp. In one corner, the current Champion SAR ADC, in the opposing corner, a relative newcomer to the analog to digital conversion scene, the Σ∆ ADC. also has a lot of mixed sig stuff on it, like a S/H so that a single SAR or a DelSig (also on many parts) plus analog mux on SAR coul;d be used.

1 \$\begingroup\$ For your application, either should work fine, but generally, an SAR ADC can run with much less power consumption than an Delta-Sigma, and most common SAR converters enter an almost zero power state unless the input changes.
