A customer is going to use TPA3221 by PBTL AD Modulation.
He says that his measurement data of TPA3221EVM THD+N is not less than 0.05 percent.
And it is worse than Typical Characteristics of the datasheet.
Q: Did the figures in 7.9 Typical Characteristics measure TPA3221EVM?
Please teach us, if you know how to get good THD+N data, except for measurement conditions described in datasheet.
