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.

Cirrus Logic tests its package types according to IPC/JEDEC J-STD-020B for Moisture Sensitivity to determine acceptable storage

conditions prior to surface mount assembly. These levels are:

MSL1 = unlimited floor life at <30

C / 85% Relative Humidity. Not normally stored in moisture barrier bag.

MSL2 = out of bag storage for 1 year at <30

C / 60% Relative Humidity. Supplied in moisture barrier bag.

MSL3 = out of bag storage for 168 hours at <30

C / 60% Relative Humidity. Supplied in moisture barrier bag.

The Moisture Sensitivity Level for each package type is specified in Ordering Information.

Note:

1. AGND is normally the same as DGND1/DGND2

2. DCVDD <= DBVDD and DCVDD <= AVDD

3. DCVDD should be >=2V when using the PLL
