Conversion rate ADC ?

adc conversion rate

im confused with various of definition ?
what is conversion rate ? is that conversion rate can be the sampling rate/freq?
Or is that sampling rate is clk speed ?
how if if a SAR ADC has clk speed of 24Mhz, requires 6 clk cycle to do conversion..so in that case what will be the conversion rate ?
How abt tis Ms/s & Mb/s ? is both same or differ ? Plz do clear me out

conversion rate of adc

hello,
that's a good inference
sampling rate - it is the rate at which the ADC took analog samples and digitize it. technically it is the rate in which the sample and hold circuit takes data

conversion rate - it is the rate at which digital signals, ADC outputs, are produce on a continous mode conversion. Normarlly, it will take a lot of clock cycles to do that. so in your case the conversion rate is 24MHz / 6 is 4 MConversion per second

conversion rate adc

thanks neoaspilet11,

how abt tis Ms/s & Mb/s ? is it same or different

conversion rate adc wiki

Ms/s=Mhz Samples per Second

but im not sure about Mb/s

maximum conversion rate adc

Could nybody tell me what is Mb/s ?

 

[Davood Amerion]

define sampling rate adc

MS/S means mega (milion) sample per second.
Mb/S means mega bit per second.
Mb/S = MS/S * n
n is number of bits per sample.
for example:
if samples is 8 bits wide, n is 8
and if sampling rate is 4MS/S then Mb/S= 4*8= 32 Mb/S

what is the conversion rate of adc

thanks for the info mr.Davood Amerion, ill appreciate much if u could help on the other question that i've been posted..about ADC timing diagram

conversion rate in adc

i think Davood Amerion's definition is right.
you canit define the performance of a adc only with the convert speed,you should also consider the resolution and which type it use.
