STw5211 combines ST-Ericsson’s playback time extender (PTE) processing technology with 102dB signal-to-noise ratio through the whole audio path, allowing OEMs to build music phones with the highest levels of audio quality and double today’s typical 10-hour playback time, said a press release.

Available as a single-chip solution in an ultra-small, wafer-level chip scale package (WLCSP), STw5211 is a cost-effective audio solution to boost playback time. It would also deliver supreme music quality with substantial improvements in handset battery life.

“ STw5211 was developed to address increasing demand for mobile music handsets with both higher audio quality and longer playback time,” said Monica de Virgiliis, vice president, Wireless Multimedia Group, ST-Ericsson.

He added that the power consumption increases as features are enhanced and quality improved; however, STw5211 with PTE technology allows music to be played autonomously while the rest of the platform is switched into a power-saving state, the release added.
