Would you help to clarify the SPI timing diagram Fig.4 below in datasheet ? It seems the SDI acquired on rising edge that is conflicted with description of pin function Table 5 on page 8. Thanks.
I have a question , AD7091R-2,-4 External Reference Input range.
There is 1.0 - Vdd V in Page 3 , at dataseat
But , there is 2.5 - Vdd in Page 18 , at dataseat.
I think external reference input range is 1.0 - Vdd .
Which is correct?
1. i want to read from channel 1 to 4 how can i do it
2.i want to do in sequence how can i do it
Using the AD7091r-2 and I want to have it sequence between chan 0 and 1 all the time.
How do I configurate that to happen?
By using external reference would it increase measurement accuracy ?
If so, which reference IC is recommended ?
Unfortunately, the only no-OS driver that exists at this moment for this family is for the single channel version - AD7091R:
Can you confirm if there is any power getting to the AD7091R-2 board? There are two LEDs in the "Power Management" section called "PWR-IN" and "PWR-GOOD" that don't appear to be lit up.
