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.
- Flash-type ADC requires no counter For an n-bit ADC, flash-type ADC requires (2n – 1) comparators
- A 4-bit ADC will have 15 comparators, and an 8-bit ADC will have 255 comparators.
- The following figure shows a 3-bit flash ADC circuit.
- It is formed of a series of comparators, each one comparing the input signal to a unique reference voltage.
- The comparator outputs connect to the inputs of a priority encoder circuit, which then produces a binary output.
- Vref is a stable reference voltage provided by a precision voltage regulator as part of the converter circuit.
- As the analog input voltage exceeds the reference voltage at each comparator, the comparator outputs will sequentially saturate to a high state.
- The priority encoder generates a binary number based on the highest-order active input, ignoring all other active inputs.

Flash Type A-D Converter:
Flash type A-D converter is the fastest among the given options. It is also known as parallel A-D converter.
Working Principle:
- In a flash type A-D converter, a set of comparators is used to compare the input voltage with reference voltages.
- The outputs of these comparators are fed into a priority encoder which generates a binary output based on the highest order active input.
Speed:
- Flash type converters provide the fastest conversion speeds because all the comparisons are made simultaneously.
- Each comparator in the flash type A-D converter operates independently of the others, leading to a very fast conversion time.
Advantages:
- High-speed conversion.
- Ideal for applications where speed is a critical factor.
In conclusion, the flash type A-D converter is the fastest among the given options due to its parallel comparison method, making it suitable for applications requiring high-speed conversion.
