2 / 69 page STw5095 2/69 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 I2C-bus compatible or SPI compatible 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 I2S compatible and they support other 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 (VCC: 1.8 V to 2.7 V), analog (VCCA: 2.4 V to 3.3 V) and loudspeaker driver (VCCLS: VCCA to 5.5 V) to obtain best performance and maximum power to the loudspeaker (up to 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.
