TLV320AIC3206: about tlv320aic3206, CM to Left MICPGA(CM1L) positive terminal selection

Part Number: TLV320AIC3206

what's the meaning of CM , what's the meaning of CM1L, 

  • 您好,CM指的是共模电压,共模电压的路径是否通过MICPGA,所以可通过寄存器Page1/R54进行配置。

    所以CM1L,其中L指的是左边MICPGA, left MICPGA,CM指的是common mode,1和2 可以看到是寄存器的bit[7:6]和bit[1:0]。同样寄存器R57是CM路径是否通过right MICPGA的配置,分别是CM1R和CM2R.
