晒出你的电路图啊,这个DA芯片本身带mute输出,如果你只是掉电出现pop音。我有个三个建议思路
1、系统电压检测芯片,如复位芯片,检测到掉电到门限,迅速复位DA芯片,或者触发mute电路。
2、保证DA芯片比控制芯片后掉电,按照规格书,如果主控与DA通讯时钟出现异常,DA会自动mute。
BMUTEC
AMUTEC
Mute Control (Output) - The Mute Control pin is active during power-up initialization, muting,power-down or if the master clock to left/right clock frequency ratio is incorrect. During reset, these outputs are set to a high impedance.
