What are the different types of a D converters?
There are really five major types of ADCs in use today:
- Successive Approximation (SAR) ADC.
- Delta-sigma (ΔΣ) ADC.
- Dual Slope ADC.
- Pipelined ADC.
- Flash ADC.
What are the different architectures types of ADC functions?
The most popular ADC architectures available today are successive approximations (sometimes called SAR because a successive-approximations (shift) register is the key defining element), flash (all decisions made simultaneously), pipelined (with multiple flash stages), and sigma-delta (SD), a charge-balancing type.
Which type of ADC is best?
Sigma–Delta ADCs–for Higher Accuracy from More Bits When you want the accuracy from more sampling bits or really need the highest effective number of bits (ENOB), sigma-delta ADCs are usually the best choice, especially for low-noise precision applications.
Which type of a D converter is fastest?
The most common types of ADCs are flash, successive approximation, and sigma-delta. The flash ADC is the fastest type available.
Which ADC is more expensive to build?
Explanation: The simplest possible A/D converter is flash type converter and is expensive for high degree of accuracy.
How do I choose ADC?
There are a few main items to consider, before selecting which ADC is best suited to your project.
- Precision/Resolution (number of bits)
- Accuracy (error in conversion)
- Speed (time for one conversion, different from clock speed)
- Voltage Range.
- Ease of Use.

What is ADC sampling rate?
The sample rate for an ADC is defined as the number of output samples available per unit time and is specified as samples per second (SPS). Two aspects of sample rate that must be considered when selecting an ADC for a particular application are the minimum sample rate and maximum sample rate.
