Note: 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 range limits and guaranteed
performance specifications are given under Electrical Characteristics at the test conditions specified.
ESD Sensitive Device. The WM8144-12 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.
As per JEDEC specifications A112-A and A113-A this product requires specific storage conditions prior to
surface mount assembly. It has been classified as having a Moisture Sensitivity level of 2 and as such will be
supplied in vacuum sealed moisture barrier bags.
