Successive-Approximation ADC
|
Detailed explanation-1: -Successive Approximation DAC has more complex circuitry than digital ramp ADC but results in faster conversions. This method is quite popular; it uses the binary search algorithm for the conversion process. It generates a sequence of approximations through all possible quantization levels.
Detailed explanation-2: -The successive approximation ADC is much faster than the digital ramp ADC because it uses digital logic to converge on the value closest to the input voltage. A comparator and a DAC are used in the process.
Detailed explanation-3: -1. Dual slope integration type ADC is the most accurate type of ADC because of non-dependency on variation in component values caused by noise.
Detailed explanation-4: -Delta-sigma ADCs () This is why they are commonly found in audio, sound, and vibration, and a wide range of high-end data acquisition applications. They are also used extensively in precision industrial measurement applications.
