PARIS Chinese embedded microprocessor supplier Ingenic Semiconductor announced it is licensing the ultra-low power audio converter from Dolphin Integration.
Ingenic Semiconductor specified that it is licensing shCOD95.BT01-Helium that Dolphin Integration claimed is a very low-power consumption 95 dB audio Codec for portable devices with headphone driver and line-out. The Grenoble-based company specified that it includes the input and output peripherals required when targeting portable applications in addition to High-Fidelity audio ADC and DAC cores.
"First, the power consumption of their DAC is amazingly low," commented Jin Zhang, CTO of Ingenic Semiconductor. "In playback mode, the total power consumption of the DAC with a Class AB headphone amplifier does not exceed 7 mW. This translates into a much longer usage on battery for our end-users."
He added: "Second, this audio Codec relies on their new and patented technology for reducing pop-up noise below an audible level. Last but not least, they have enhanced their audio Codec architecture to significantly reduce the out-of-band noise, which shall facilitate the performance appreciation by our users, even those which do not own test equipment dedicated to audio measurement."
In the meantime, Dolphin Integration said it has enhanced its ViC-set with embedded peripherals, as low-jitter oscillators and linear regulators, to reduce both the risk upon integration for SNR and the bill of material.
