Note 5. All voltages with respect to ground.
Note 6. AVSS 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.

Note 7. When the LDOE pin = âLâ VDD18 must be powered up either at the same time or after TVDD is
powered up. The power up sequence between AVDD and TVDD or AVDD and VDD18 is not critical.
Note 8. When LDOE pin = âHâ, the internal LDO supplies 1.8V (typ). The power up sequences between
AVDD and TVDD, AVDD and VDD18 are not critical.
