Grenoble, France, — February 03, 2009 — Helium is a family of audio Virtual Components combining the best solutions for low power consumption and Density while offering high audio resolution for portable applications.
Optimization of the performances depending on usage conditions is made feasible in Helium thanks to the availability of two innovative operating modes: a "nomad" mode, enabling low power operation for the longest music playback with stereo headphones, and a "dock" mode for an optimized output signal to drive resident external speakers.
"The concept is really simple", explains Hélène Colin, Audio Product Line Manager, "When listening to the MP3 player, the needed output power is far below the full-scale level required for driving external speakers. The Nomad mode reduces power consumption for typical listening power levels, while providing a very low noise floor, thus delivering a high audio quality.
Moreover Helium requires a simple application schematic for reducing the number of external components on PCB (lower Bill-of-Material) and its high density also reduces silicon costs.
Already available: the Digital to Analog Converter Helium DAC in SMIC 0.11 um process.
