Hi!

The AD7492 datasheet says that the internal 2.5 V reference is available for external referencing. The EVAL-AD7492SDZ User Guide showing the connection of REF OUT with +input of the AD8021AR what have typical Input Bias Current 7.5 uA.
I want to connect the voltage divider (750 kOhm+32 kOhm) to the output REF OUT of the AD7492BRUZ and join the midpoint of the divider with a non-inverting input of the AD8066. Could this load affect the AD7492BRUZ?
