TAS5711: EVM usage question

Bonnie Chen
Intellectual 1160 points
Part Number: TAS5711


Hi team,

can you help to check below questions? We cannot find on datasheet/application note on EVM.

The scenario happened in 2.1 mode only and no issue in 2.0 mode.

 

we would like to confirm 2.1 mode algorithm detail of TAS5711 for connect speaker project.

Except BQ4a control, any low-pass filter existed on below differential path and we can't control flexibly?

We plan to use 1 pcs full-range speaker(5Wx1) on differential path, and 2pcs tweeters(10Wx2) on single-end paths. 

Full-range speaker played a main role for music playback(not only traditional woofer function).

    Hi Bonnie,

    It seems that you want to implement 2.1 mode. As to the 'woofer', you want a full range rather than a woofer. Hence, you set BQ4a as all pass.

    With the GDE configuration, have you find any issue? Does audio in woofer path come out as it is filtered by a low pass filter?

    If so, send me waveform indicating this issue and the configuration file for my check in EVM.

    Regards,

    Alix Wan.
