Note 1. All voltages with respect to ground.
Note 2. AVSS, DVSS, VSSL and VSSR must be connected to the same analog ground plane.
Note 3. Connect at least 0.1uF or more decoupling capacitors between VDDL/VDDR and VSSL/VSSR to
suppress affections by a static electricity noise or an over voltage (includes over shooting) that exceeds
absolute maximum ratings.
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 4. The power up sequence between AVDD, VDDL/R and DVDD is not critical.
Note 5. The analog output voltage scales with the voltage of (VREFH  VREFL).
AOUT (typ.@0dB) = (AOUT+)  (AOUT) = 2.8Vpp  (VREFHL/R  VREFLL/R)/5.
