28377的ADC通道问题

您好!

    我在手册上看到28377的ADC结构图上是有16个输入通道,一共有ADCA、B、C、D四个模块,但在芯片引脚图中是看到ADCAIN0~5,即每个ADC有6个输入通道,而且输入引脚是固定的? 而ADCIN14和ADCIN15是独立的,请问这个要怎么理解?

  • 这个pin是四个ADC的公共pin,可以当做任意一个ADC的采样口,建议用作ADC的矫正。

    Input 14 to all ADCs. This pin can be used as a general-purpose ADCIN pin or it can be used to calibrate all together (either single-ended or differential) froman external reference.
