Note 4. All voltages with respect to ground.
Note 5. 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 4. All voltages with respect to ground.
Note 6. The power-up sequence between AVDD, VDDL/R and DVDD is not critical.
Note 7. The analog output voltage scales with the voltage of (VREFH  VREFL).
AOUT (typ.@0dB) = (AOUT+)  (AOUT) = 2.8Vpp  (VREFHL/R  VREFLL/R)/5.
* TVDD must be powered up befor or at the same time of DVDD when the LDOE pin = “L”.
* The internal LDO outputs DVDD (1.8V) when the LDOE pin = “H”. The power-up sequence between
VDDL/R and TVDD or VDDL/R and AVDD is not critical.
* AKM assumes no responsibility for the usage beyond the conditions in this data sheet.
