WM8150
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.
The WM8150 has been classified as MSL1, which has an unlimited floor life at <30
o
C / 85%C Relative Humidity and therefore will
not be supplied in moisture barrier bags.

GND denotes the voltage of any ground pin.
AGND1, AGND2 and DGND pins are intended to be operated at the same potential. Differential voltages
between these pins will degrade performance.
