NOTES
1. ABSOLUTE MAXIMUM RATING specifies the values beyond which the device may be damaged permanently. Exposure to
ABSOLUTE MAXIMUM RATING conditions for extended periods may affect reliability. Each condition value is applied with the
other values kept within the following operating conditions and function operation under any of these conditions is not implied.
2. All voltages are measured with respect to VSSA unless otherwise specified.
3. 100pF capacitor is discharged through a 1.5KW resistor (Human body model)

NOTES
1. It is strongly recommended that all the supply pins (VDDA, VDDAL) be powered from the same source to avoid power latch-up.
