with integrated power amplifiers  
Features  
Dual 20 bit audio resolution, 8kHz to 96kHz  
independent rate ADC and DAC  
Dual I2S or PCM digital interfaces for dual  
STw5098  
master  
Sustain complex voice and audio flow with or  
without mixing  
I2C/SPI compatible control I/F  
Asynchronous sampling ADC and DAC: they  
do not require oversampled clock and  
information on the audio data sampling  
frequency (fs). Jitter tolerant fs  
LFBGA 6x6x1.4 (112 pins)  
VFBGA 5x5x1 (112 pins)  
Wide master clock range: from 4MHz to 32MHz  
Stereo headphones drivers, handsfree  
Description  
loudspeaker driver, line out drivers  
Mixable analog line inputs  
STw5098 is a dual low power asynchronous  
stereo audio CODEC device with headphones  
amplifiers for high quality audio listening and  
recording.  
Voice filters: 8/16kHz with voice channel filters  
Automatic gain control for microphone and line-  
in inputs  
Two I2S/PCM digital interfaces are available, one  
per master for example Bluetooth and Application  
Processor, enabling concurrent audio and voice  
flow between Network and user.  
Frequency programmable clock outputs  
Multibit Σ∆ modulators with data weighted  
averaging ADC and DAC  
DSP functions for bass-treble-volume control,  
mute, mono/stereo selection, voice channel  
filters, de-emphasis filter and dynamic  
compression  
The STw5098 control registers are accessible  
through a selectable I2C-bus compatible or SPI  
compatible interface.  
93 dB dynamic range ADC, 0.001% THD with  
full scale output @ 2.7V  
95 dB dynamic range DAC, 0.02% THD  
performance @ 2.7V over 16load  
Applications  
Digital cellular telephones with application  
processor such as mp3 or gaming and  
Bluetooth concurrent application
