my project includes sampling the voice using ADC and storing the data in flash memory and finally retreiving it from memory using DAC. The platform being 89c51 microcontroller
1.) i've made a basic preamplifier and checked it's o/p on CRO and it's amplitude is limited to 1V. I want to know whether my ADC could sample such variations.
2.) Please tell me some power amplifier configuration
(if possibly LM 386)to test the o/p of this circuit , by connecting it at o/p of this circuit,without connecting it to microcontroller.

most of the ADC i/p varies from 0-5V for FSD , so u have to amplify the signal 5 times to get the full resolution of the adc.
