Hi Team,
For the TAS5719 reference design uses the 220uF cap on the PVDD.
Could you let me know what is the concern if only implement 47uF on the PVDD?
If using 3 pcs 47uF on the PVDD, will that be ok?
Thanks,
SHH

Hi SHH,
The EVM takes input from a power supply into the banana cable input. Since the power supply is unknown with the EVM the decoupling has to be conservative, hence the 220uF cap. Please refer to pages 20 and 58 of the datasheet for guidelines on choosing decoupling cap values. 220uF cap is not mentioned there.
2) Audible noise is 20 to 20,000 Hz.
5) It is an open loop amp
1,3,4,6) It sounds like most of your other follow up questions were contingent on needing the 220uF cap. Please let me know if the customer still has questions about them now that they do not need this cap and I can look in to them further. Also I would need the schematic to answer some of them.

Hi Alex,
For customer's PCB, how to determine the bulk cap values?
For page58, I believe it is use for the headphone bulk cap. Can you confirm?
Thanks,
