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. TVDD must be powered up before VDD18 when the LDOE pin = “L”. The power up sequence
between AVDD and TVDD or AVDD and VDD18 is not critical.
Note 8. When LDOE pin = “H”, the internal LDO supplies 1.8V (typ). The power up sequences between
AVDD and TVDD, AVDD and VDD18 are not critical.
Note 9. VREFL1 pins must be connected to AVSS. Connect a capacitor which is 10µF or more to the each
VREFH1 pins. (Figure 77)
