Note 1. All voltages with respect to ground.
Note 2. AVSS, DVSS, VSSL and VSSR 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.

Note 1. All voltages with respect to ground.
Note 3. The power up sequence between AVDD, VDDL/R and DVDD is not critical.
Note 4. The analog output voltage scales with the voltage of (VREFH  VREFL).
AOUT (typ.@0dB) = (AOUT+)  (AOUT) = 2.8Vpp  (VREFHL/R  VREFLL/R)/5.
