Digital audio hub
EDN Europe, 01 Mar 2010The WM8995 by Wolfson Microelectronics is a digitalaudio- hub solution for mobile phones, improving battery life and music-playback time, and providing more enduser features at lower cost, compared to a less integrated solution, while allowing concurrent operation of several systems. It will port, mix and route audio streams from multiple processors to multiple transducers. Featuring various audio interfaces with sample- rate conversion and digital mixing, plus a simple interface to speaker amplifiers that enable the minimum PCB footprint, the WM8995 also incorporates a dual capless Class W headphone driver, which enables outputpower limitation in countries that have legal limits for headphone power. The WM8995 also features next-generation digital filters that offer more natural sound during voice calls, and a two-pin serial audio data interface for transmitting PDM data to digital input speaker amplifiers.
