Other Parts Discussed in Thread: TAS5805
Hello,
Our customer used TAS5805 and met two questions when tested its performance.
1.There is too much idle noise of speaker, it is about -53dB, and it could be heard by people。
2. When played sweep frequency, the power of the speaker is increased with the frequency increase, he configured 10W power, and it could get to 25W, but when played 1KHz file, it couldn't appear this phenomenon. But if he jumped the I2S, I2C, fault and PDN pins of EVM to his own board, he couldn't hear noise, and didn't appear the power is changed with frequency. His setting is the same with EVM board. In addition, PVDD=13.5V, and the load is 4ohm.
Could you please help to analyze it?
Best regards
Kailyn
