Advantages:

o It is economical method of analog to digital conversion.

o The resolution is up to 5 important digits are obtained.

Disadvantages:

o Incorrect reading is obtained when the noise signal is occurred.

o The filter is used to reduce the noise signal which also reduces the total speed of operation.

o The accuracy of the whole system is depends on accuracy of digital to analog converter and accuracy of internal reference supply.

o The speed of operation is restricted. The speed is depends on which type of switches are used.

o The conversion time required for digital to analog converter.
