STW5095 Datasheet - STMicroelectronics

Description
STw5095 is a low power asynchronous stereo audio CODEC device with headphones amplifiers for high quality audio listening and recording.

FEATUREs
■ 20 bit audio resolution, 8kHz to 96kHz
   independent rate ADC and DAC
■ 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
■ I2C/SPI compatible control I/F
■ 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
■ Two programmable master/slave serial audio
   data interfaces (I2S, SPI, PCM compatible and
   other formats)
■ 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 mp3 player,
   stereo recorder, fm radio stereo listening and
   recording functions, live music recording
■ Portable digital players and recorders
