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 VREFLL/R pin must be the same voltage as VSS.
The analog output voltage scales with the voltage of (VREFH − VREFL).
AOUT (typ.@0dB) = (AOUT+) − (AOUT−) = ±2.4Vpp × (VREFHL/R − VREFLL/R)/5.
