An AVR IS connected to the 8mhz crystal oscillator Calculate

An AVR IS connected to the 8mhz crystal oscillator. Calculate the ADC frequency.
a. ADPS2:0 =001
b.ADPS2:0=100
c. ADPS2:0=111

Solution

It’s given as AVR is connected to 8MHz crystal oscillator.

The ADC frequency = clock /Division factor

Bits 2:0 – ADPS2:0: ADC

These bits determine the division factor between the XTAL frequency and the input clock to the ADC.

So
