ADS1292R的datasheet中有一处不明白

时间:10-02 整理:3721RD 点击:

第37页,RDATA的时序图中,DOUT波形的注解写着:“Status Register+ 8-Channel Data (216 Bits)”

不明白这个“8-Channel”,“216 Bits”是怎么来的?ADS1292R不是只有2个通道么,何来8通道?或是此处本身有误?

写的有问题。看29页,应该是72bit。

The number of bits in the data output depends on the number of channels and the number of bits per channel.
For the ADS1292R, the number of data outputs is (24 status bits + 24 bits × 2 channels) = 72 bits. The format of
the 24 status bits is: (1100 + LOFF_STAT[4:0] + GPIO[1:0] + 13 '0's). The data format for each channel data is
twos complement, MSB first. When channels are powered down using user register settings, the corresponding
channel output is set to '0'. However, the sequence of channel outputs remains the same.

是的,前面看得好好的,看到那里突然就觉得不对劲。

谢谢解答,这下放心了
