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.
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.

Analogue and digital grounds must always be within 0.3V of each other.
The digital supply core voltage (DCVDD) must always be less than or equal to the analogue supply voltage (AVDD)
DCVDD must be lower than or equal to DBVDD.
USB Mode should not be used with DCVDD lower than 2V
If DBVDD is lower than 2.5V, DCVDD must be at least 0.225V lower than DBVDD.
If DBVDD is higher than or equal to 2.5V, DCVDD must be lower than or equal to DBVDD.
USB Mode should not be used with DCVDD lower than 2V
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.
