    hi all
    i m working on my project
    well a problem arise that how i give 0-5 VOLTS to a ADC, i use many amplifier circuits, but didn't succeed to get a 0-5V amplification
    if any one have IDEA about such amplifier, then plz mention here, or post comments
    i shall be thankfull to him

    My advice to you is to calm down. The circuits in your first postings is as my first guess something you found on the web.
    As a starter you should give us more details about your project. Now it seems more or less that you are fishing for an easy way out of some school project.
    Anyway if you are using a microphone i guess you are trying to sample sound. If you are going to fit this into a 0-5 volt ADC you will in first hand need a amplifier after the microphone. As the microphone output usually is low level. Also since you have a unipolar ADC with range 0 to 5 volt you need a level translator. Sound is AC you have to shift the signal with +2.5 volt before you feed it to the ADC.

    i just want to trace pitch of AUDIO SIGNAL
    and i have 8 channel ADC, in which 8 inputs are to be given
    well, i have to find the ptch of sound in each and every mic, so thats why i need amplifier
