I use AIN0 and AIN1, single-ended input, AIN1 as GND.
The internal reference 1.2 V is used.
Can I connect Vbias generator through AIN11/VBIAS1 to reference InAmp (AD8221),
And output AD8228 connect to AIN0 (in main case)?
What is Vbias current?
As explained on page 28 of the User Guide - depending on the load up to typ. 150µA max.
So the 50 to 60 µA for the AD8221 REF input are available, but you must enable the boost mode.
