Cirrus Logic Bows High-Res Audio DAC With Headphone Amp for Mobile Devices

Responding to growing demand for high-fidelity music playback from mobile devices, Cirrus Logic bowed the CS43130 MasterHiFi digital-to-analog converter (DAC) with built-in headphone amplifier, it announced Tuesday. A non-oversampling emulation mode is said to provide “warmth” associated with tube amplifiers for a natural sound said to be missing from contemporary products. The CS43130 uses 512 DACs per channel and an analog/digital filter array for reproduction of high-bandwidth, high-res digital audio sources to filter out noise and jitter, said Cirrus. “Smartphone OEMs worldwide are accelerating product development efforts to give consumers a better listening experience that takes advantage of the growing accessibility to high resolution streaming and downloadable music content,” said Carl Alberty, Cirrus Logic vice president-audio products. Total harmonic distortion plus noise measures -108 dB, dynamic range is given as 130 dB, and the DAC supports up to 32-bit, 384 kHz sample rates, including Direct Stream Digital up to DSD128, it said. Advanced hi-fi filters allow OEMs to tune their own signature sound, said the chipmaker.
