Dear,
Do you mind help me to solve this problem? The appendix is the schematic diagram.
At present, when customers are using TPA3221, the gain of both the master mode and the slave mode is set to 26db, the master mode is PBTL, and the slave mode is BTL. The master mode is connected to 2 Ω/no load, there is also a problem, The performance is that the sound of the master mode is lower than that of the slave mode.
Many thanks!
Crystal.
