Audio ADC and DAC is needed

    Audio ADC and DAC is needed !!

    I am looking for Audio ADC and DAC.
    Anyone can give their advice on choosing these two converters?
    I am planning to convert the Analog audio to Digital Signal (vice versa) in 10 – 16 resolution bits and fs max will be 44.1kHz.

    what is the different between single-ended or differential input for that?

    What have you found so far in your searching the Internet? You have used some good keywords in your question -- what happens when you google them?

    Take a look at the website for Analog Devices -- they should have some good devices and application notes to get you started.

    At first, i thought it will be easy to pick one ADC and DAC from net or Analog device, but after i look for the spec, it show upto 100 choices...
    so i wonder what shud i take more care on it.. i plan to make it as simple as well... but due to the signal is audio, so it may need higher requirements? or anything will does?

    To refine your search, I googled Audio ADC and DAC +44.1kHz, and got lots of good hits:

    http://www.google.com/search?source...GLL_enUS301US302&q=Audio+ADC+and+DAC++44.1kHz

    Have a look through that hit list to see if you find something you like. You need to find a good Application Note on how to actually build something like this. It's not an easy project, if you want good audio quality in the end. What kind of projects have you built so far?

    Actually, i need to convert the audio output from my CD player to digital form then transmit it wireless by laser...
    let put the quality aside, as least i want to convert it into Digital.. i looked for the ADC for 1week d... but i really not sure which will be the suitable 1... even 8 or 10bits also can.

    Can you just use a CD player with a digital output built-in?

    That would simplify at least that part of the project.

    I know at one time the company Burr-Brown had DACs that were used in CD players.

    Thanks for the links.
    but i think to convert the analog signal to digital is part of my responsibilities.
    anyway, still need to figure out the way to get compatible ADC with DAC...
