CODEC Interfacing with TI Smart Amp

Other Parts Discussed in Thread: TAS2557, PCM2706C, PCM2912A

Hello,

Is there a CODEC that can interface with a host through I2S or USB and a smart speaker amp (such as TAS2557) through I2S?

Regards,

Gui

    Hi Gui,

    Are you looking for a CODEC with I2S input and I2S output? Is it possible that you could share a block diagram for a better understanding of what you're looking for?

    Hi Ivan,

    I apologize for the delay. I have included a simple block diagram below. I am looking for the lowest complexity solution that allows for a TI smart amp (I2S input).

    Thanks,

    Gui

    Gui,

    PCM2706C could be useful for the USB Hub to I2S interface. Although it doesn't support Mic input. It is only DAC and I2S output, there is no analog input available.
    PCM2912A could be used as USB to analog output interface, and it also features Mic input. But this device doesn't have I2S interface to connect with TAS2557. You would need to use an ADC to take the analog output of PCM2912A into I2S for TAS2557.
