Advanced Information

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. GND denotes the voltage of any ground pin.

2. AGND1 − 6 and DGND1 − 5 pins are intended to be operated at the same potential. Differential voltages

between these pins will degrade performance.
