ADAS3022 Recommended Circuit Help

I see in the Recommended circuit schematic for the ADAS3022 ADC that the ADR434 is to be used for providing the 4.096 V reference voltage. When I considered the ADR434 datasheet, I see that it is meant to operate at a voltage from 6V-18V. The Recommended circuit for the ADAS3022 designates that a 5V input should be given to the ADR434. Is this correct? If not, how can the circuit be adjusted to consider this? Any assistance would be appreciated.

    Hi codigwe,

    Seems you follow the recommended setting for the reference circuit.It should be able to power the ADR435 with a  +15V supply. . Aside from ADAS3022 and ADR435 what other components connected to this? it draw current if the total impedance excess  than  expected. I should check first the  power supply circuit.Try to limit the connection on this. Please take note ADP1612/13 as per datasheet page3 Vout=12V  ILoad is limited to 10mA to 150mA.

    regards,
