24-bit DAC delivers high audio quality for mobile music apps

Geneva, Switzerland — STMicroelectronics has introduced a high-performance 24-bit audio digital-to-analog converter (DAC) that offers a 103-dB dynamic range across the entire audio path. Aimed at the mobile music market, the STw5200 offers high audio quality with on-chip management, which enables a reduced footprint and direct connection to a battery. The audio DAC is available in small TFBGA and VFQFPN packages, and soon, in a tiny 2.6 x 2.6-mm WLCSP.

Integrated power management, which eliminates the need for an external voltage regulator, together with a built-in 50 mW “true-ground” headset amplifier, which operates without coupling capacitors, are said to simply system implementation and shrink the footprint. The device's high level of integration is made possible by ST's 0.13-micron analog CMOS process.

Pricing: $1.60 in quantities of 1,000. The chip is packaged in a 4 x 4 x 1.2-mm TFBGA40, with a 0.5-mm ball pitch, and a 7 x 7 x 1-mm VFQFPN44, with a 0.5-mm pitch. A 2.6 x 2.6 x 0.65-mm WLCSP36 packaged version, with a 0.4-mm ball pitch, is planned for introduction in the third quarter of 2008.
Availability: Samples are available now to lead customers, with volume production planned for March 2008.
Datasheet: STw5200
