Hi.
I use the TPA3110. My question is POP Noise.
The first pop noise appears after power up.
It does not come out after that.
SD terminal is not used.

Hi Qin
The circuit diagram is the same as attached.
The PCB module is purchased as a finished product.
There is no pop noise when Sig-R, Sig-L (R2) are removed.
Waiting for good news.

HI Junho,
These two varistors (R2) are not needed. Please refer our TPA3110D2EVM Audio Amplifier Evaluation Board (Rev.B) for guidance.
Rdgs,
Matt
