+======  Analog-to-digital converter for audio signals - ADCaudio01B ======
+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 [[https://www.cirrus.com/products/wm8786/|WM8786]].
+The main parameters are as follows:
+  	* Sampling frequency 8 - 192 kHz
+	* Distortion - 102 dB
+	* I²S  interface
+	* 24 bit resolution
+	* SNR 111 dB
+===== ADCaudio01A =====
+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
+  * DACSEL0 az DACSEL3 = L
+For WM8786 a following configuration is functional:
+  * MS0 = L
+  * AUDIOF0 = L
+  * AUDIOF1 = H
+  * OSR0 = 0
+  * OSR1 = 0
+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.//**
