WM8960
Stereo CODEC with 1W Stereo Class D Speaker Drivers and
Headphone Drivers for Portable Audio Applications
DESCRIPTION
FEATURES
The WM8960 is a low power, high quality stereo CODEC
designed for portable digital audio applications.
Stereo class D speaker drivers provide 1W per channel into 8
loads with a 5V supply. Low leakage, excellent PSRR and
pop/click suppression mechanisms also allow direct battery
connection to the speaker supply. Flexible speaker boost
settings allow speaker output power to be maximised while
minimising other analogue supply currents.
A highly flexible input configuration for up to three stereo
sources is integrated, with a complete microphone interface.
External component requirements are drastically reduced as no
separate microphone, speaker or headphone amplifiers are
required. Advanced on-chip digital signal processing performs
automatic level control for the microphone or line input.
Stereo 24-bit sigma-delta ADCs and DACs are used with low
power over-sampling digital interpolation and decimation filters
and a flexible digital audio interface.
The master clock can be input directly or generated internally by
an onboard PLL, supporting most commonly-used clocking
schemes.
The WM8960 operates at analogue supply voltages down to
2.7V, although the digital supplies can operate at voltages down
to 1.71V to save power. The speaker supply can operate at up
to 5.5V, providing 1W per channel into 8 loads. Unused
functions can be disabled using software control to save power.
The WM8960 is supplied in a very small and thin 5x5mm QFN
package, ideal for use in hand-held and portable systems.

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.
Wolfson 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 <30C / 85% Relative Humidity. Not normally stored in moisture barrier bag.
MSL2 = out of bag storage for 1 year at <30C / 60% Relative Humidity. Supplied in moisture barrier bag.
MSL3 = out of bag storage for 168 hours at <30C / 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. DCVDD must be less than or equal to AVDD and DBVDD.
4. AVDD must be less than or equal to SPKVDD1 and SPKVDD2.
5. SPKVDD1 and SPKVDD2 must be high enough to support the peak output voltage when using DCGAIN and ACGAIN
functions, to avoid output waveform clipping. Peak output voltage is AVDD*(DCGAIN+ACGAIN)/2.
