Hi
I would like to know settling time of VREF and various.


Turn-on Settling time say 5msec @CFER=10uF

But REF OUTPUT current is about 300uA.
If VREF setting is 4.096, then
4.096 X 10u /300uA=136mSec

Is it correct understanding?

 

What "Turn-on settling time"  definition is?

Hw long will it need settled VREFout ?
How various of that time? 30%?

 

Regards

Moto
