Codec's channels

Tom_Gean · ‎2024-03-27

Hi, I hope finding an answer this is my first time asking you.

So, I'm trying to build a CLASS_D AMPLIFIER with codec (STA309A).

This codec has 8 input channels for serial AUDIO and I want to play more channels for the codec's inputs but the I2S can only transmit the data in stereo mode.

Welcome @Tom_Gean, to the community!

Well, if you look at the STA309A data sheet, you will find four input pins for four I2S dual channels = 8 channels (SDI_12/DSD_3, SDI_34/DSD_4, SDI_56/DSD_5, SDI_78/DSD_6). So you are not only feeding in with one I2S, but with four I2S.

Does it answer your question?
