A/D converter question

[jyothika]

can someone tell me "How long will an 10 bit Analog/Digital convertor take to complete its conversion approximatly?"
? clock pulses
does it depends on the number being converted?
Need your help ...thank u

It depends on the design of the converter.
There are flash converters which can do the conversion in a single cycle and sucessive approximation ones that measure one bit at a time.
Then of course it depends on the overall clock rate - you could have a 1Mhz flash converter and a 10GHz succesive approximation.

Many real workd designs are a combination of both, using flash for the high bits and then approximating the low bits. Some designs do depend on the number of on-bits in the answer, they are a pain to work with.
