Description

SoC integrators wishing to address portable audio applications like MP3 players, PMP or Application Processors for mobile communication, should demonstrate the best sound quality, while starring the longest playback capability.
shDAC95-Helium, the ultra low power audio converter, is thus the best ally of SoC integrators targeting such high volume markets. Its amazingly small area ensures a cost-effective SoC integration both in mature and very advanced pure logic processes.
This audio converter proves it feasible to combine Class-AB amplifiers, known for offering the lowest Bill-of-Material, with ultra-low dynamic power.

Features
  • Patented PLL-less solution to avoid jitter issue due to audio PLL on SoC.
  • Pop-Up Noise Reduction system
  • High audio performances measurable with test equipment not specific to audio measurement.
