Lightning EarPods耳机、转换头拆解：都有DAC

越南网站Tinhte分享了对苹果新款Lightning EarPods耳机、Lightning-3.5mm转换头的拆解，证实二者都有小小的DAC数模转换芯片。

其中，耳机内的芯片编号为338S00140 / A0QK1623 / TW，转换头里的则是338S00140 / A0MU1621 / TW，都有金属屏蔽罩，覆盖了两层金属，但没有任何厂商标识。

不过，苹果一般都是从凌云逻辑(Cirrus Logic)采购音频相关芯片，他们家正好也有DAC芯片，更何况编号里还有TW(台湾)字样。

DAC的加入，可以让分新的Lightning EarPods、传统3.5mm耳机都能通过Lightning接口正常工作，后者输出的是数字音频。
