I'm looking for a fast 16-bit ADC module that I can use in a project. The ADSxx15 chips will not work, their sample rates are far too slow.
I made a TCP-enabled streaming FM radio server with a Mega2560 + TEA5767 + W5500. I'm sampling the line out from the TEA (with a +2.5v bias added to center the signal in the ADC's voltage range) with the Arduino's onboard ADC on a timer interrupt. I buffer and send the audio in real-time through a small HTTP server I wrote. It can be played through VLC, etc on a client computer and the tuner frequency can be adjusted through a web interface.
It works well, I can sample the audio at 22 KHz mono with more than enough CPU headroom to stream live to multiple network clients. The only problem is the low resolution of the ADC, it sounds pretty decent but 16 bit would be a nice jump in quality.
Any good IC's out there that are reasonably easy to interface with an Arduino, and can sample at 22 KHz or better in a 16-bit resolution?
I'm probably going to post this project on here with code this weekend if anybody else is interested. It honestly works a lot better than I expected with just a simple AVR.
