Hello,
I'm confusing about SLAU279A 's figure 8.
Since DAC9881 is designed as bufferd output mode, so internal buffer may lead offset voltage and headroom voltage.
They may crash the linearity of DAC. My problem is:
Q: When analysis the linearity, how to identification the non-linearity due to buffer's offset voltage & headroom voltage ? Is there are some definition about them ?
Thank you!
