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.

Cirrus Logic tests its package types according to IPC/JEDEC J-STD-020 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.

Notes:

DCVDD must not be powered if AVDD is not present.

The AVDD1 and AVDD2 pins should be tied together. The associated power domain is referred to as AVDD.

The AGND1 and AGND2 pins should be tied together. The associated ground domain is referred to as AGND.

The HPOUT1FBn and MICDETn functions share common pins. The Absolute Maximum Rating varies according to the

applicable function of each pin.

CP1VOUT2N is an internal supply, generated by the WM8281 Charge Pump (CP1). The CP1VOUT2N voltage may vary

between AGND and -CPVDD.
