ADCaudio01B is an innovated version of an older module, with an already integrated crystal oscillator that eliminates the need for a further module that served as an external generator of a sampling clock. It uses ADC WM8786.
The main parameters are as follows:
* Sampling frequency 8 - 192 kHz * Distortion - 102 dB * I²S interface * 24 bit resolution * SNR 111 dB
For testing purposes we used module [en:usbi2s|USBI2S01A]] as a host.
For CP2114, a configuration 0 works without a further setting up - so in case of CS42L55
For WM8786 a following configuration is functional:
Board as connected as followed:
| ADCaudio01A | direction | USBI2S01A |
|---|---|---|
| MCLK | ⇐ | MCLK |
| BCLK | ⇐ | SCK |
| LRCLK | ⇐ | LRCK |
| DOUT | ⇒ | SDIN |
There seems to be a crosstalk between L and R channel.
