tlv320aic3206 audio ADC?

[markkimball]

First post here. Owner of a Teensy 4.0, writing code with the Arduino IDE on Ubuntu 18.04.

I'm working on a couple of non-audio applications* that need 192KSPS@16 bits, which I believe eliminates the SGTL5000. I note that the audio library source code on github includes a driver for the TI tlv320aic3206, which can sample at 192KSPS. PJRC doesn't offer a board with this part on it so I'm wondering how folks (if any) are using the TI part. Are they using the TI demo board, their own design or ???. And if the driver found on github works OK or needs some work.

Thanks
Mark

Hi,

I helped write that driver. I wrote it because I helped make the Tympan, which is an open source audio processing platform that is a teensy 3.6 at its heart combined with a AIC3206, Bluetooth, battery, etc.

We also did a floating point version of the Audio Library to take advantage of the Teensy 3.6's floating point math capabilities.

Thank you for the information. I'll take a look at the info on github.
