With multiple, mixable analog inputs and outputs, the STw5095 can directly drive stereo headphones without external capacitors, and 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, as well as mixed with DAC audio signals. 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 into most audio systems. It supports an extended master clock range (any value between 4 and 32 MHz) and multiple audio data rates, which are independent in AD and DA paths. Moreover, it tolerates jitter on audio data without downgrading performance. The audio data serial interfaces (for AD and DA) can be master or slave, are I2S compatible and also support other formats for easy interfacing to standard serial ports. The internal D to A and A to D converters work with up to 24-bit resolution. Evaluation board * Complete-user friendly play-and-learn application board with software * Easy software development on target application * Application features complete MP3 player and FM radio receiver * Interactive schematics and register display windows that exercise any chip configurations in real-time at a click of a mouse * Instant system analog connection and activation * Handset, headset and speaker connectors * Compliant with Windows XP/NT/2000/Millennium and 98 LET'S CREATE IT (c) ST-Ericsson, 2009 - All rights reserved.
