    Hi Brian,

    It is ok for the reference voltage to be higher than the supply voltage when using ADS8861. VREF = 5 V and AVDD = DVDD = 3.3 V is an acceptable configuration (this is very similar to the test conditions at the top of the Electrical Characteristics table Slight smile ).

    Best regards,

    Ryan
