ABSOLUTE MAXIMUM RATINGS
(VSS1-4 = 0V; Note 1)
Parameter
Power Supplies:
Input Current, Any pin Except Supplies
Digital Input Voltage
Ambient Temperature (Power applied)
Storage Temperature
Note 1. All voltages with respect to ground.
Note 2. VSS1-4 must be connected to the same analog ground plane.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Voltage Reference
(Note 4)
“L” voltage reference
VREFH-VREFL
Note 1. All voltages with respect to ground.
Note 3. The power up sequence between AVDD and DVDD is not critical.
Note 4. Analog output voltage scales with the voltage of (VREFH
VREFL).
AOUT (typ.@0dB) = (AOUT+)
(AOUT
) =
±
2.8Vpp× (VREFHL/R
VREFLL/R)/5.
