Description
STw5095 is a Low Power Asynchronous Stereo Audio CODEC device with Headphones Amplifiers for
high quality audio listening and recording.
The STw5095 control registers are accessed through a selectable I
interface.
The STw5095 Asynchronous Stereo Audio Codec is designed to easily fit in most audio systems because
it supports an extended master clock range (any value between 4 MHz and 32 MHz) and at the same time
it supports any audio data rate (independent in AD and DA paths) from 8 kHz to 48 kHz and from 88 kHz
to 96 kHz, moreover it can tolerate jitter on audio data without degrading performance. The audio data
serial interfaces (for AD and DA) can be Master or Slave, are I
formats that can easily interface to standard serial ports. The two audio interfaces can be used as a single
bidirectional interface. Two frequency programmable Clock Sources are available to generate the master
clock for the audio sub-system of other devices. The internal D to A and A to D converters work with up to
24 bit resolution.
The supply voltage can be the same for the whole device, in the range 2.4 V to 2.7 V, or it can be
differentiated for digital (V
(V
500 mW).
STw5095 has multiple analog mixable inputs and outputs. It can directly drive Stereo Headphones without
external capacitors and it has a Loudspeaker driver that can also be used for monophonic group listening.
Stereo differential and single ended microphones, auxiliary line in stereo and mono signals can be mixed
and connected to the ADC or directly to the drivers, mixed also with DAC audio signals.
STw5095 Stereo Audio Codec main applications include multimedia handheld devices such as cellular
phones with added low-power high-quality MP3 and⁄ or FM radio listening/recording features, or any
battery powered equipment such as PDAs, Camcorders, etc. that require Stereo Audio Codec with
Headphones drivers.
