WM8785 General Description
The WM8785 is a stereo audio ADC with differential inputs designed for high performance recordable media pplications. Data is provided as a PCM output.
Stereo 24-bit multi-bit sigma-delta ADCs are used with digital audio output word lengths of 16 to 32 bits, and sampling ates from 8kHz to 192kHz. The device has a selectable high pass filter to remove residual DC offsets. The device also s upports a TDM bus for data out.
The device is controlled via a 2 or 3 wire serial interface. The interface provides access to all features including oversam pling rate, audio format, powerdown, master/slave control and digital signal manipulation. The device is supplied in a 0-lead SSOP package.
WM8785 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/ 85% Relative Humidity. Not normally stored in moisture barrier bag.
MSL2=out of bag storage for 1 year at <30 / 60% Relative Humidity. Supplied in moisture barrier bag.
MSL3=out of bag storage for 168 hours at <30/ 60% Relative Humidity.Supplied in moisturebarrierbag.
Note: Analogue and digital grounds must always be within 0.3V of each other.
