Hi TI team,
My customer designed TAS2559.
There are some problems.
1. The output is saturated at 1.3W. they want a 3.5W @THD 1% spec.
2. The output of 1khz is 12db lower than other frequency bands.
3. The same phenomenon occurs when the same PPC3 setting is applied to the EVM.
Attached the ppc3 setting value. please check it.
If you have a reference PPC3 setting file to apply to EVM, please provide it.
Thanks,
Downey Kim.
