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
