Notes: 1. All voltages with respect to ground.
2. AVSS, BVSS and DVSS 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.

Notes: 3. The power up sequence between AVDD and DVDD is not critical.
4. Analog output voltage scales with the voltage of (VREFH-VREFL).
AOUT (typ.@0dB) = (AOUT+) - (AOUT-) = ±2.4Vpp×(VREFH-VREFL)/5.
