WM8750L

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 WM8750L has been classified as MSL1, which has an unlimited floor life at <30oC / 85% Relative Humidity and therefore will

not be supplied in moisture barrier bags.
