STMicroelectronics has unwrapped a very high performance 24-bit audio digital to analog converter (DAC) that is intended for the mobile music market. Implemented in 0.13-micron analog CMOS process, single-chip STw5210 provides 103 dB signal-to-noise ratio through the whole audio path, while also embedding the company’s innovative Playback Time Extender (PTE) processing scheme to minimize power consumption. This audio solution also integrates power management circuitry to simplify system design and enable direct connection to the battery, and is available in small TFBGA and VFQFPN packages. And will also be soon offered in a tiny 2.6 x 2.6mm WLCSP package, said ST.

The integrated power management and the built-in 50mW headset amplifier, which operates without coupling capacitors, ensures easy system implementation, minimum bill of materials (BOM), and a very small footprint.

Samples of the STw5210 are available now to key customers, with volume production planned for March. It is packaged in a 4 x 4 x 1.2 mm TFBGA40, with 0.5 mm ball pitch, and a 7 x 7 x 1 mm in QFN44, with 0.5 mm pitch. A 2.6 x 2.6 x 0.6mm WLCSP36 packaged version, with 0.4 mm ball pitch, is planned for introduction in the third quarter.. The DAC is priced at $1.80 in quantities of 1000 units.
