Hello i using atmega32 for sampling the analog signals. with 16 Mhz crystal i think i will get 16mhz/128=125khz adc clock frequency
then what would be the maximum analog frequency i can sample with this circuit?
 

The Atmel ATmega series offers a maximum sample rate of 15kSPS at a resolution of 10 bits.

Reference: ATmega32(L) Datasheet, Section: Analog to Digital Converter, Page: 201


Conversion Timing is discussed in the same datasheet on page 204.

i want to know what would be the max analog signal frequency i can apply at adc input practically for proper sampling..
 

nyquist says...

15KHz/2 = 7.5KHz

so your input signal better have all of it's frequency components below 7.5KHz if you want "good" sampled data.
