- ADC in Atmega8
- Posted by Sam on April 30th, 2006
Hello,
I am doing a project using ATmega8. For that we need an ADC of atleast
5Msps. We first thought of using the built in ADC but I want to know
the maximum samples per second for the in built ADC? I guess it is
around 150Ksps but I am not sure. Can I increase this sample rate by
loading the prescalar value like one or 2? Could someone help.
Thanks
with regards

No, it will not do anything like that speed. Even if it did, you would
not be able to process the data fast enough to do anything with it...

The data sheet, table 103, says that max clock speed for the ADC is 1
MHz, and a "normal" conversion takes 13 clock cycles. The "brag tape" at
the beginning of the description of the ADC says "Up to 15 kSPS at
maximum resolution"...
