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

The AVRs are known for their slow ADCs.

I've used the ATmega88 and I remember that the maximum sample rate of
the ADC was around 15Ksps.

If there's something you don't know about a chip you are using, it's
usually a good idea to at least glance at the data sheet. You'll find
the information you are seeking in the first paragraph of the ADC
section.
