Hi TIer
I want to ask a question, is the nominal sampling rate of this chip in the range of 16-96 for any of the L and R channels? So are there two ADCs inside the chip to collect the voltages of the two channels respectively? Or an ADC for time-division multiplexing?
Thank you very much.
There are 2 ADC inside the chip. The digital output of both ADC 's is available on DOUT pin of the ADC. It comes as serial sdata on a single line. The image below shows
how the 24 bit data appears on DOUT Pin. To make the ADC work we need to provide the following input signals.
SCKI A good value of SCKI is 256*Fs or 12.288Mhz
BCK A good Value is 64 *Fs or 3.072Mhz
LRCK A good value is 48K. This makes an Fs or sampling rate of 48Khz.
The Digital Data for the 2 Channels appears on DOUT
