I’m trying to capture signals using 6 x AD7912 ADC’s wired in daisy chain. I can’t get it to work the way it is described in the datasheet.
It seems there is an error in the datasheet. In figure 34 of the datasheet of the AD7912…
I'm using AD7912 to convert analog signals to digital. However, I checked the DOUT by oscilloscope and found out that the DOUT signal is keep in low potential. I have check the SCLK, CS, DIN, analog in, VDD and GND are all correct. Clock is at the…
所以需要请 ADI 工程师帮忙确认问题所在！
For 12 Bits, single channel SAR, look at AD7920, the AD7910 is the 10 bit version of this part.
If you need more channels then look at AD7912 (2 channel) AD7923/7 (4 channel/8 channel).
For a 12 bit sigma delta look at the AD7170.
