AVR-Chat

Hi, my friend wants to use the ADC of an AT90s8535, but 
she is not sure how. i never had any experience using 
AVR's ADC. My friend told me that there is still some 
external circuit to be made. Is this true? What is the 
purpose of this external circuitry?

And what are the limitations of AVR's ADC? Is is slow 
compared to simple ADCs like 0804/0809?

Thx.
Irfan.
