PCM6240-Q1: 与硅麦麦克风连接

Part Number: PCM6240-Q1

Hello Ti Engineer,

    我们有一款硅麦麦克风与PCM6240连接,麦克风的基本参数和推荐接口电路如下图所示,请帮忙确认:

  1. 如果使用DC-Coupled,是否可以直接按照PCM6240的Datasheet中DC-Coupled Single-Ended Input的框图连接,备注:MIC无声音输入时,MIC输出保持在DC 2.54V;
  2. 如果使用AC-Coupled,PCM6xx0-Q1 AC Coupled Rext Calc 表格中的Vrms我应该设置成什么值;
