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.

  • Dear LLoben,

    Thank you very much for your reply. Would this mean that I should be able to power the ADR434 with the +15 V rail and keep all of the other connections in the recommended circuit the same? I have tried this, and I am experiencing strange behavior with the circuit drawing up to 200 mA in current without the ADAS3022 being operational. Please let me know of any changes that can correct this problem.
