AD7767:  How is the maximun input current on the VREF  Pin?

Hi Jonathan,

We have two AD7767 in our application and  want to use one reference only.

Figure 46 in the Datasheet Rev.0 is differ to Datasheet Rev.C.

Can the reference ADR434 drive 100μF ?

Should a separate reference be used for each AD7767 or is it better to use a reference and an 2 op amp (AD8032)  to drive the reference input ?

Regards,

Ludwig
