loudspeaker driver, line out drivers
Mixable analog line inputs
Voice filters: 8/16kHz with voice channel filters
Automatic gain control for microphone and line-
in inputs
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
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

VFBGA 5x5x1 (112 pins)
Description
STw5098 is a dual low power asynchronous
stereo audio CODEC device with headphones
amplifiers for high quality audio listening and
recording.
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.
The STw5098 control registers are accessible
through a selectable I2C-bus compatible or SPI
compatible interface.
