WM8962
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 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:
1. Analogue, digital and speaker grounds must always be within 0.3V of each other.
2. All digital and analogue supplies are completely independent from each other (i.e. not internally connected).
3. AVDD must be less than or equal to MICVDD.
4. AVDD must be less than or equal to SPKVDD1 and SPKVDD2.

Notes:
1. SPKVDD1 and SPKVDD2 must be high enough to support the peak output voltage when using CLASSD_VOL function, to
avoid output waveform clipping. Peak output voltage is AVDD*CLASSD_VOL.
2. The AGND and PLLGND pins must be tied together as close as possible to the WM8962.
3. The WM8962 can operate with PLLVDD tied to 0V; device power consumption may be reduced, but the crystal oscillator, PLLs
and CLKOUT functions will not be supported.
