TAS2781: cancel echo using TAS2781

Charlie Xiao

Part Number: TAS2781

Hi BU team,

Can TAS2781 collect the output signal of the speaker to SoC for echo cancellation? Do I still need to use an additional ADC to collect the output signal of the speaker? Thanks.

Regards,

Hi Charlie,

Yes TAS2781 can transmit the processed audio dat to be used for echo cancellation. No additional hardware is needed.

this can be configured in Audio processing > TDM panel. "Audio out" is the echo reference data

Arthur
