STw5095

Low-power asynchronous stereo audio Codec

with integrated power amplifiers

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 16

Ω load

Analog inputs

■ Selectable stereo differential or single-ended

microphone amplifier inputs with 51dB range

programmable gain

■ One microphone biasing output

■ Microphone plug-in and push-button detection

input

■ Selectable stereo differential or single-ended

line inputs with 38 dB range programmable

gain

Analog output drivers

■ Stereo headphones outputs driving capability:

40 mW (0.1% THD) over 16

Ωwith 40 dB range

programmable gain

■ Common mode voltage headphones driver

(phantom ground)

■ Balanced loudspeaker output driving

capability: up to 500mW (VCCLS>3.5V; 1%

THD) over 8

Ω with 30dB range programmable

gain

■ Transient supression filter during power up and

power down

■ Balanced/unbalanced stereo line outputs

driving capability 1k

Ω

Applications

■ Digital cellular telephones with mp3 player,

stereo recorder, fm radio stereo listening and

recording functions, live music recording

■ Portable digital players and recorders

Description
