Hi-fi audio quality DAC

6 August 2008 Analogue, Mixed Signal, LSI

STMicroelectronics has developed a very high-performance 24-bit audio DAC (digital-to-analog converter) that offers 103 dB dynamic range across the entire audio path. The new STw5200 is available in small TFBGA and VFQFPN packages, and soon, in a tiny 2,6 x 2,6 mm WLCSP. Simplifying the system design, the DAC can also be directly connected to a battery in a mobile device.

The device, offering line and headset outputs, meets the increasing demand for higher audio quality from mobile music applications and is ideal for any platform where audio quality needs to be boosted to Hi-Fi level. It also integrates power management, which eliminates the need for an external voltage regulator, and by the built-in 50 mW 'true-ground' headset amplifier, which operates without coupling capacitors.
