大家好,TLV320AIC3106有MIC3R MIC3L两个引脚,我看EVM上做MIC输入时这两个引脚接在一起用,我想问,能不能用这两个引脚单独各接一路MIC输入,从而形成两路MIC输入?或者大家可有支持两路MIC输入的芯片给推荐一款。

从 TLV320AIC3106 器件主页的介绍看:
The record path of the TLV320AIC3106 contains integrated microphone bias, digitally controlled stereo microphone preamplifier, and automatic gain control (AGC), with mix/mux capability among the multiple analog inputs.
既然是支持 stereo microphone , 那么应该是两路MIC 能够分别输入
