Hi. I use in system a few AD7606s with one external reference. In data sheet on page 24 Figure 41 shown 0.1uF capacitors on each REFIN of ADCs and 10uF cap near reference.
But in Circuit Note CN-0148 where are 10uF on REFINs. So where is the truth?
I use in my scheme AD780 reference IC with 10uF tantalum and 0.1uF ceramic capacitors on output.
What current this ADC give from reference?
P.S. Sorry for my English
