DESCRIPTION
GPIO Pin 1 / PCM interface clock
GPIO Pin 2 / IRQ (Interrupt Request) output
GPIO Pin 3 / PCM frame signal
Pre-Production
GPIO Pin 4 / ADA (ADC data available) output or Mask input /
PCM input (DAC) data
GPIO Pin 5 / SPDIF digital audio output / PCM output (ADC) data
Die Paddle (Note 1)
It is recommended that the GND_PADDLE is connected to analogue ground. Refer to the "Recommended External
Components" diagram and "Package Dimensions" section for further information.
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-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.
The Moisture Sensitivity Level for each package type is specified in Ordering Information.

Difference AGND to DGND
Note:
1. AGND is normally the same as DGND1/DGND2
2. DCVDD <= DBVDD and DCVDD <= AVDD
3. DCVDD should be >=2V when using the PLL
