Dolphin Integration Announces a Breakthrough for an Embedded Output Converter for high quality Audio

March 23, 2005 - The leading Provider of Virtual Components for high-performance audio announces a breakthrough for an audio DAC to embed in a System-on-Chip.

Stand-alone Output Converters can be found for quality Audio at prices as low as 30 to 40 cents per chip when fabricated in large quantities. System-on-Chip Integrators thus wonder how to enhance their SoC competitiveness while maintaining their sales margins:

LoDAC is their Audio DAC of choice, as it relies on a PWM architecture with Class D amplifier, with an innovative solution, the patent of which is pending.

Offered with diverse configurations, loDAC can be as small as 32,500 gates to deliver audio performances as high as 95 dB for SNR with a sampling rate up to 192 kHz!

In addition, as a pure logic virtual component, loDAC is far less sensitive to noise than conventional delta-sigma converters and can be safely embedded in large logic SoCs.

For applications requiring high output power, a configuration of loDAC can emit up to 500 mW per channel which demonstrates a power efficiency as high as 90%! Such a configuration ends-up being as small as 1.2 mm2 in most 0.18 um processes.

Furthermore, proposed in a filter-less configuration, loDAC significantly reduces the bill-of-material of the system maker.

Such capabilities, position loDAC as the preferred solution for SoCs targeting MP3, DVD, DSC, DVC, Car Audio, Mobile Phones, etc.

Two handy collaterals are available, one FOR FREE to guide the assessment of return-on-investment and one FOR RENTAL: an evaluation board to prepare the SoC integration plan.
