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-A this product requires specific storage conditions prior to surface mount

assembly and as such will be supplied in vacuum sealed moisture barrier bags.

Note 1:

AGND denotes the voltage on any analogue ground pin.

DGND denotes the voltage on any digital ground pin.

CGND denotes the voltage on the clock ground pin.

For this device all GND pins should be star connected as close as possible to the device.

Note 2:

AVDD denotes the voltage on any AVDD pin.

For this device all AVDD supplies should be connected together.
