DAC5686: DAC5686输出的P,N端区分

Part Number: DAC5686

Hi,

有两个问题：

1. IOUTA1，IOUTA2和IOUTB1，IOUTB2，这两对差分哪个是P端？哪个是N端？在规格书上看不出来。

但是从参考电路上去看IOUTA1，IOUTB1是N端，IOUTA2，IOUTB2是P端。这个理解对吗？

2. 哪对是接I信号？哪对是接Q信号？

    您好，您的理解是对的，或者数据手册Analog Current Outputs这部分也提到了，IOUT1是positive端，IOUT2是Negative端。

    如果使用dual bus mode，DA可以接I，DB接Q，但是如果使用Interleave Bus Mode，I和Q都接在DA channel上。
