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 susceptible to damage

from excessive static voltages. To optimise the distortion and noise performance of pins 3, 4, 13 and 14, the

on-chip ESD protection circuitry has been restricted, and consequently only achieves 300V when characterised

to the Human Body Model. Proper ESD precautions must be taken during handling and storage of this device.

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.
