STMicroelectronics Intros 24-bit Audio DAC for Mobile Music Applications

(Product News, 4 Feb 2008)

STMicroelectronics (ST) has released a high-performance 24-bit audio DAC (digital to analog converter) that is intended for the mobile music market and provides 103dB signal-to-noise ratio. Integrated with ST's PTETM Playback Time Extender processing scheme, the single-chip STw5210 audio solution minimizes power consumption, and is available in small TFBGA and VFQFPN packages and, soon, in a 2.6x2.6mm WLCSP.

The chip integrates power management circuitry to simplify system design and enable direct connection to the battery, For more advanced multimedia smart phones, the STw5210 is also an ideal match for ST's STn8810/8815 Nomadik multimedia processor family and its companion STw4810/4811 power management unit, as well as the TS4962 high-efficiency Class D audio power amplifier for loudspeaker outputs. The chip is also ideally suited for any mobile music application based upon competitive companion devices, but especially in mobile phone platforms where playback time is likely to see the greatest increase.
