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
