4. Which of the following is the fastest type of ADC successive approximation conversion?

Which ADC is the fastest ADC?

Flash ADC (Fastest)

The flash ADC is the fastest type available. A flash ADC uses comparators, one per voltage step, and a string of resistors.

Which type of ADC is fastest in its operation 1 point integrating type Delta Sigma Flash successive approximation?

A flash type ADC produces an equivalent digital output for a corresponding analog input in no time. Hence, flash type ADC is the fastest ADC. The 3-bit flash type ADC consists of a voltage divider network, 7 comparators and a priority encoder.

Which type of ADC is best?

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 of the following is the fastest type of ADC successive approximation conversion?

Flash type ADC is fastest ADC.
