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.
As per JEDEC specifications A112-A and A113-B, this product requires specific storage conditions prior to surface mount assembly
and will be supplied in vacuum-sealed moisture barrier bags. It has been classified as having a Moisture Sensitivity Level of 2.

Notes:
• GND denotes the voltage of any ground pin. AVDD denotes the voltage applied to any AVDD pin.
• AGND and DGND pins are intended to be operated at the same potential. Differential voltages between these pins will degrade
performance.
