STw5098
Dual low power asynchronous stereo audio Codec
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
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
■ Wide master clock range: from 4MHz to 32MHz
■ Stereo headphones drivers, handsfree
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 16Ω load
Applications
■ Digital cellular telephones with application
processor such as mp3 or gaming and
Bluetooth concurrent application

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.
