    详细询问下ADS8363数据输入输出的 控制方法!

都知道输入是如下:

CHB1P/CHB3 1 AI Fully-differential noninverting analog input channel B1 or pseudo-differential input B3
CHB1N/CHB2 2 AI Fully-differential inverting analog input channel B1 or pseudo-differential input B2
CHB0P/CHB1 3 AI Fully-differential noninverting analog input channel B0 or pseudo-differential input B1
CHB0N/CHB0 4 AI Fully-differential inverting analog input channel B0 or pseudo-differential input B0
CHA1P/CHA3 5 AI Fully-differential noninverting analog input channel A1 or pseudo-differential input A3
CHA1N/CHA2 6 AI Fully-differential inverting analog input channel A1 or pseudo-differential input A2
CHA0P/CHA1 7 AI Fully-differential nonInverting analog input channel A1 or pseudo-differential input A1
CHA0N/CHA0 8 AI Fully-differential inverting analog input channel A1 or pseudo-differential input A0

条件一  :采用模式3 M0/M1 1 0  Automatic SDOA and SDOB

条件二  :采用模式全差分方式

问题1:采用全差分模式后,是否可理解为4路差分信号输入,每路分为P/N?即全差分模式实际上是可以输入4路差分信号。

问题2:此时有CHA0N-----CHA1P   4PIN,和CHB0N-----CHB1P   4PIN是否可理解为输出SDOA 对应CHA0N-----CHA1P   4PIN,and 输出SDOB对应CHB0N-----CHB1P   4PIN?如果不是具体过程如何?


 

  • 1:采用全差分模式后,是否可理解为4路差分信号输入,每路分为P/N?即全差分模式实际上是可以输入4路差分信号。
    是的.

    2:此时有CHA0N-----CHA1P 4PIN,和CHB0N-----CHB1P 4PIN是否可理解为输出SDOA 对应CHA0N-----CHA1P 4PIN,and 输出SDOB对应CHB0N-----CHB1P 4PIN?
    是的, 但条件是 M1 要为低电平
