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.
