Compact DAC offers easy installation

Integrated power management and a built-in 50mW 'true-ground' headset amplifier reduce the system footprint and ease system implementation.

STMicroelectronics has released a 24bit audio DAC (digital-to-analogue convertor) that offers a 103dB dynamic range across the entire audio path.

Aimed at the mobile music market, the new STw5200 is available in small TFBGA and VFQFPN packages and soon in a 2.6 x 2.6mm WLCSP.

Simplifying the system design, the DAC can also be directly connected to the battery.

The new DAC, offering line and headset outputs, meets the increasing demand for higher audio quality from mobile music applications and is suitable for any mobile phone platform where audio quality needs to be boosted to a Hi-Fi level.

Easy system implementation, minimum bill of materials (BOM) and a very small footprint are ensured by integrated power management, which eliminates the need for an external voltage regulator and the built-in 50mW 'true-ground' headset amplifier, which operates without coupling capacitors.

The STw5200 extends ST's audio DAC and ADC family, with enhanced audio performance.

The device's high level of integration is made possible by ST's 0.13-micron analogue CMOS process.

The chip is packaged in a 4 x 4 x 1.2mm TFBGA40, with 0.5mm ball pitch and a 7 x 7 x 1mm VFQFPN44, with 0.5mm pitch.

A 2.6 x 2.6 x 0.65mm WLCSP36 packaged version, with 0.4mm ball pitch, is planned for introduction in Q3 2008.
