Here is my question.
We want to send the AD5308 a 10-bit value instead of 8-bit for reasons of software compatibility.
The AD53x8 datasheet isn’t clear on this, it says:
“The AD5318 uses 10 bits and ignores the 2 LSBs. The AD5308 uses 8 bits and ignores the
last 4 bits. These ignored LSBs should be set to 0."
So our question is, what if those extra LSBs are NOT set to zero, will that be a problem?
As far as I remember those bits are ignored.
