Note 2. All voltages with respect to ground.
Note 3. AVSS, DVSS, VSSL and VSSR must be connected to the same analog ground plane.
Note 4. Connect at least 0.1μF 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 2. All voltages with respect to ground.
Note 5. Each power-up/down sequence is shown below.
<Power-Up>
1. PDN pin = “L”
2. TVDD (1.8V) power-up
3. AVDD, DVDD (3V) power-up
4. VREFHL/R and VDDL/R (5V) power-up
5. The PDN pin is allowed to be “H” after all power supplies are applied and settled.
otherwise power up the 1.8V power supply, the 3.3V power supplies and the 5V power supplies at
the same time.
<Power-down>
1. PDN pin = “L”
2. VREFHL/R and VDDL/R (5V) power-down
3. AVDD, DVDD (3V) power-down
4. TVDD (1.8V) power-down
Note 6. The analog output voltage scales with the voltage of (VREFH  VREFL).
AOUT (typ.@0dB) = (AOUT+)  (AOUT) = 2.8Vpp  (VREFHL/R  VREFLL/R)/5.
