Be ready to share your mobile STw5098 dual, low power, stereo audio codec with integrated amplifiers The STw5098 is a dual, high-quality stereo codec with headphones and hands-free amplifiers. It is dedicated to mobile phones supporting several audio sources (modem, digital audio such as MP3 or gaming, Bluetooth, FM radio, etc.) and performing complex audio flows. The two available I2S/PCM digital interfaces - one per master -enable concurrent audio and voice flow between the network and user. With the STw5098, the audio capabilities of your mobile are no longer restricted. For example, it allows you to record yourself singing, while at the same time enabling your sister to talk to her friends.

It allows simultaneous utilization of audio applications, enabling different users to share the same mobile phone. The STw5098 has multiple analog mixable inputs and outputs. It drives stereo headphones directly, without external capacitor 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 ADCs or directly to the drivers, and also mixed with DAC audio signals. 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 configuration in real time at a mouse click *Instant system connection and activation *Handset, headset and speaker connectors *Compliant with Windows XP/NT/2000/Millennium and 98 Examples of use * Voice over Bluetooth with concurrent handheld gaming *Mixing MP3 with voice during a conference call, then recording it * Audio playback with speaker/headphone/Bluetooth * Recording all line-in and microphones * Voice calls with or without recording LET'S CREATE IT (c) ST-Ericsson, 2009 - All rights reserved.
