Successive Approximation ADC:

Successive Approximation ADC is the very common type of ADC today and it is used in many general-purpose applications.

The major components of this ADC are the comparator, Digital to Analog Converter, and Successive Approximation Register.

In this ADC, the output of the DAC is compared with the input signal (which is sampled using the sample and hold circuit) and based on the comparator output, the output of the Successive Approximation Register is changed (One bit at a time)
And the output of the SAR is given as an input to the DAC.

Conversion Time: (No . of bits of the ADC ) x (Clock Cycle)

In this ADC, the conversion time is independent of the input signal.

Advantages of SAR ADC:

1) Good Accuracy
2) Fast Conversion
3) Low Power Conversion
4) Easy to Use
5) Low Latency Time
