What are the advantages and disadvantages of a flash type ADC?
Block diagram of Flash ADC The advantage of this converter is the speed with which one conversion can take place. The disadvantage of the Flash ADC is the area and power requirements of the 2 N-1 comparators. The speed is limited by the switching of the comparators and the digital logic.
What are the disadvantages of flash type AD converter?
Disadvantages: 1)It is not suitable for higher number of bits. 2)To convert the analog input voltage into a digital signal of n-bit output, (2n – 1) comparators are required. The number of comparators required doubles for each added bit.
What is the main limitation of analog to digital conversion?
Limitation #2 – An ADC can only be used with one pin at a time. Voltages on multiple pins need to be measured one after the other (this is usually not such a big deal if the ADC is fast). The third element in the circuit is the sampling capacitor, and the resistance of the input circuit and multiplexer feeding it.
What is the disadvantage of using Flash Type A to D converter?
Which one of the following is a disadvantage of R 2R type of digital to analog converter?
A disadvantage of the former DAC design was its requirement of several different precise input resistor values: one unique value per binary input bit. Manufacture may be simplified if there are fewer different resistor values to purchase, stock, and sort prior to assembly.
What is the advantages of using flash type ADC converter?
Explanation: Flash type ADC has the advantage of high speed as the conversion takes place simultaneously rather than sequentially. Typical conversion time is 100nanosecond or less. Explanation: The number of comparator required almost doubles for each added bit.

What is an analog-to-digital converter (ADC)?
An analog-to-digital converter (ADC) is a system that converts an analog signal to a digital signal. For example, a sound picked up by a microphone into a digital signal.
What is the fastest type of ADC?
Flash analog to digital converter is the fastest type of ADC among all the other ADCs. It is also known as a parallel analog to digital converter. It comprises high-speed comparators, resistive voltage divider circuits along with a priority encoder.
What are the advantages and disadvantages of ADC?
Advantages: It is more accurate ADC type among all. It has greater noise immunity compare to other ADC types. Disadvantages: It is the slowest ADC among all. In order to achieve better accuracy, it requires high precision external components.
What is the difference between ADC and DAC?
There are numerous ADC architectures, but some of the specific ADCs ate implemented as ICs (integrated circuits) due to the complexity and the requirement for exactly matched components. A digital-to-analog converter (DAC) performs the reverse function; it converts a digital signal into an analog signal.
