STW5094AD Detalles de producto

GENERAL DESCRIPTION
STw5094A is a low power asynchronous stereo audio DAC device with headphones amplifiers for high quality MP3 and FM radio listening. The STw5094A includes also an high performance low power combined PCM Codec⁄ filter tailored to implement the audio front-end functions required by low voltage low power consumption digital cellular terminals with added MP3 and FM radio listening.

FEATURES
■ Complete stereo audio digital to analog
   converters and filters
   – 18-bit, 8 kHz to 48 kHz DAC with sample-rate
      conversion
   – Linear phase analog&digital filters
   – 16 Ω load stereo headphones drivers, 8 Ω
      load mono loudspeaker driver for group
      listening
■ Stereo audio DAC features
   – Asynchronous sampling DAC: does not
      require oversampled clock and information
      on the audio data sampling frequency.
      Jitter tolerant
   – Multibit Σ∆ modulator with data weighted
      averaging DAC
   – 92 dB dynamic range, 0.01% THD over 16 Ω
      load performance
   – Support any sampling frequency in the range
      8 kHz to 48 kHz
   – DSP functions for bass-treble-volume
      controls, deemphasis filter and dynamic
      compression
   – Tones from tone generator can be injected in
      the audio paths
■ Stereo headphones and loudspeaker/earpiece
   power amplifiers features and stereo input for
   FM radio features:
   – 20 kHz bandwidth stereo headphones
      outputs. Driving capability: 40 mW
      (typ. 0.1% T.H.D) over 16 Ωwith 40 dB range
      programmable gain
   – Balanced earpiece⁄ loudspeaker output.
      Driving capability: 300 mW (typ. 0.1% T.H.D)
      over 8 Ωwith 30dB range programmable gain
   – Analog stereo input for FM radio with 38 dB
      range programmable gain
■ Complete CODEC and filter system
   – 14-bit linear or 8-bit companded ADC and
      DAC
   – Transmit and receive digital band-pass filters
   – Active antialias and smoothing filters
   – 8 Ω load earpiece/loudspeaker driver,
      16 Ω load auxiliary driver
■ Voice CODEC features
   – Support 8 kHz or 16 kHz sampling rate
   – One microphone biasing output
   – Remote control function
   – Three switchable microphone amplifier
      inputs. 42.5 dB range programmable gain
   – Transient supression during power up and
      power down
   – Internal programmable sidetone
   – Internal ring, tone and dtmf generator
   – Programmable PWM buzzer driver (Continue ...)
  
APPLICATIONS
■ CDMA,GSM,DCS1800,PCS1900,JDC digital
   cellular telephones with MP3 and FM radio
   stereo listening functions
■ Portable devices with a stereo digital audio
   source and FM radio listening function
