Hi All,
I like to use the Spartan 3E Starter kit as audio capture/playback developping system as it has Linear Technology's DAC and ADC built in. Ideally I want to be able to connect it to a computer speaker and microphone just like a computer sound card. But I guess it requires some external analog circuit and also the line-in and line-out connector to interfac with the DAC and ADC.
Is there any reference design avaialbe for this type of external circuit? Or if there is any commercial expansion/add-on card to support this purpose that works with Spartna 3E Starter Kit?
Thanks a lot!
William
