WM8960GEFL/RV 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.

WM8960GEFL/RV Thermal Information
The speaker and headphone outputs can drive very large currents. To protect the WM8960 from overheating a thermal shutdown circuit is included and is enabled by default. If the device temperature reaches approximately 150 0 C and the thermal shutdown circuit is enabled (TSDEN = 1; TSENSEN = 1) the speaker and headphone amplifiers (HP_L, HP_R, SPK_LP, SPK_LN, SPK_RP, SPK_RN and OUT3) will be disabled. This feature can be disabled to save power when the device is in standby mode.
TSENSEN must be set to 1 to enable the temperature sensor when using the TSDEN thermal shutdown function. The output of the temperature sensor can also be output to the GPIO1 pin.

| REGISTER ADDRESS | BIT | LABEL | DEFAULT | DESCRIPTION |
|---|---|---|---|---|
| R23 (17h) Additional Control (1) | 8 | TSDEN | 1 | Thermal Shutdown Enable 0 = Thermal shutdown disabled 1 = Thermal shutdown enabled (TSENSEN must be enabled for this function to work) |
| R48 (30h) Additional Control (4) | 1 | TSENSEN | 1 | Temperature Sensor Enable 0 = Temperature sensor disabled 1 = Temperature sensor enabled |
