ST-Ericsson has announced its latest audio digital-to-analogue converter (DAC) for the mobile music market - the STw5211. It combines ST-Ericsson's Playback Time Extender (PTE) processing technology with 102dB signal-to-noise ratio through the whole audio path.
According to ST-Ericsson, this will allow OEMs to build music phones with improved audio quality and double today's typical 10-hour playback time.
The STw5211 is available as a single-chip solution in a 2.6 x 2.6 x 0.6 mm, 0.4 mm pitch wafer-level chip scale package (WLCSP).
"Typically, 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. This results in a substantial increase in battery life without any compromise in audio quality for the consumer."
Volume production of STw5211 is planned for August 2009, with samples available in April.
