A New Offering of High-Resolution Audio DACs for Resident Consumer Applications by Dolphin Integration

Grenoble, France -- September 29, 2008 -- Dolphin Integration, a premier supplier of audio Virtual Components of IP announced today the enrichment of its set of Digital Audio Converters (DACs) for resident consumer applications.  The loDAC family of audio converters relies on PWM conversion to drive external Class-D and Class-AB power amplifiers.
 
loDAC audio converters are proposed with different Signal to Noise Ratios (SNR) to cover a wide range of applications: from the entry level Set-Top-Box, and now up to the high-end DVD player needing 5.1 channel processing with a SNR up to 110 dB!
 
Such audio converters are based on a fully logic design with a small gate count: the more advanced the process, the lower the silicon area!
A stereo audio DAC in a 65 nm process is as small as 0.2 mm2 with no need for any audio PLL to generate the sampling frequencies…
 
The increasing volume of SoCs fabricated for such applications makes the integration of the audio DAC highly competitive, declares Jean-François Pollet, Chief Innovation Officer at Dolphin Integration. Moreover Fabless companies praise such DACs for the ease of their integration into large logic SoCs, usually known as very noisy for analog converters.
Our solutions not only provide the highest SNR within the smallest silicon area, but also embed an innovative clock management system to enable the synchronization between audio and video frequencies.
 
The patents registered by the company also ensure the best protection of its users for such PWM DAC, in an area known for being crowded with solutions also protected by patents.
 
The set of configurations available with the loDAC family can be implemented following various application schematics to fit application requirements in terms of Bill-of-Material and performances: Set-Top-Boxes, DVD players/recorders, Multimedia HDD and Digital TV...
