TAS2780: Questions for TAS2780

Part Number: TAS2780

Hi team,

My customer has some problem for TAS2780，please help to recommend.

 1. VSNS_P/N connection to behind EMI filter option?

2. Please help to advise value of ESD component.

3. Cf1 and Cf2 have to recommend CAP value 1nF at datasheet. Do you have other spec suggestion for Vdc and ESR? And MTK only suggest component equivalent cap must <330pF in Audio AMP output path? Do you have another suggest value?

Thanks

    Hi Paul,

    Here are the recommendations on the three items that you mention.

    1. Connect VSNS_P and VSNS_N as close as possible to the speaker. Use 4.7K resistors for connecting speaker terminals with VSNS_P and VSNS_N.

    2. Customers can use ESD components as per their system need.

    3. TI EVM use Cf1 and Cf2 value of 1nF and pick the cap voltage ratings depending on desired max output voltage of the amplifier.

    Regards,
