Production Data  
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.  
Wolfson 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.

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.
