TLV320AIC3206: Is it possible to Daisy Chain this part?

Joel Murphy

Part Number: TLV320AIC3206


I would like to know if It is possible to interface with two of these CODECs to get 4 channel sound.

I have looked around and I don't see a mention of how to do it in the datasheet or any of the app notes.

    Hi, Joel,

    Welcome to E2E, Thanks for your interest in our products!.

    The 'AIC3206 is a Stereo audio codec, this part can be configured to operate in TDM mode, which enables the sharing of the digital audio bus among different devices, allowing the use of two 'AIC3106s for a 4-channel application.

    One thing to consider is that the I²C address of the 'AIC3206 is fixed to 0x30, so it will be required to add an I²C bus mux to use two devices with the same bus.

    Best Regards,

    Thanks Diego,

    It's a shame that the I2C address can't be modified. But, I guess that TI also sells a bus muxer ;)
