TAS5704: Does 350uV Noise Floor Make Sense with the TAS5704?

Part Number: TAS5704

Hi Sirs,

With 24V PVCC, 6.8ohm load, does 350uV noise floor make sense with the TAS5704? My customer's found 240uV noise floor ith most of their TAS5704 devices, however, there is one corner case with 350uV noise floor. We can duplicate high noise floor problem with this chip on another system board.

Would you pls advise if 350uV noise floor make sense with the TAS5704 device? How to identify this noise floor problem if we can duplicate it on the EVM (we are planning to mount this NG chip to the EVM)? I got ~200uV noise floor on the EVM with a good TAS5704 device as a reference.

TAS5704 EVM:


Thank you and Best regards,
