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
