CASE
All Power Supply voltages are referred to AGND, the reference signal ground, unless othewise specified.
Note 1:
Note 2:
Not production tested.
User should use a precision supply for VREF setting because the offset and gain of all DACs will change
proportionately to a deviation from VREF = 2.500V. See Equations 1 and 5 to determine the extent of
offset and gain change to deviations in VREF.
