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

w
Analogue and digital grounds must always be within 0.3V of each other.
All digital and analogue supplies are completely independent from each other.
Analogue supply voltages should not be less than digital supply voltages.
In non-boosted mode AVDD2 should be ≥ AVDD1. In boost mode, AVDD2 should be ≥ 1.5 x AVDD1.
DBVDD must be greater than or equal to DCVDD.
Analogue supply voltages should not be less than digital supply voltages.
DBVDD should be ≥ 1.9V when using the PLL.
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.
