ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at
or beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical
Characteristics at the test conditions specified
ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible
to damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage
of this device.

Notes:
1.
Analogue and digital grounds must always be within 0.3V of each other.
2.
The digital supply core voltage (DCVDD) must always be less than or equal to the analogue supply voltage (AVDD) or
digital supply buffer voltage (DBVDD).
3.
The digital supply buffer voltage (DBVDD) must always be less than or equal to the analogue supply voltage (AVDD).
