SLAA788A这个文档我没找到,能把您的电路发一下看看吗?输入端是如何接的?
上电时序是否满足datasheet中的上电要求?不知BST电容您使用的多大的,建议0.22uF~0.47uF之间。
能把您的电路图附上看下吗?
输出配置的是什么模式,BTL模式吗?
能否将reset从high到low,以及low 到high的波形附上看下,噪声大概多少?
您好,我这边收到的回复如下:也就是说可能是因为输出端OUTP和OUTM不匹配导致的POP声。
if adjusting C_start doesn't work, can you also check whether the LC filter difference is too large so that the outp and outm not matching.
