The increased adoption of high-resolution audio sources has strengthened the demand for high-fidelity audio equipment that can deliver an equally high sound quality. Moreover, higher-level designs of audio ICs are required to pursuit of high-fidelity audio.
The basis of 50 years of expertise in developing audio ICs has allowed ROHM to establish ‘sound quality design technology’ capabilities for high-fidelity audio equipment that is close to the original sound source. ROHM offers products designed with an emphasis on sound quality; including sound processors and power supply ICs under the audio device brand, ‘ROHM Musical Device MUS-IC’.
During last year’s hifideluxe, ROHM showcased the D/A converter IC, which is one of the most important components to determine the quality of audio equipment, for the first time as a test chip.
This year, ROHM will demonstrate the newest D/A converter IC ‘BD34301EKV’ which has achieved an outstanding performance and will be mass-production this fall.
The BD34301EKV 32bit, 2ch Sigma-Delta-D/A converter IC:
- Available for 22.4MHz DSD signal and 768kHz sampling PCM signal.
- Numerical performance of SNR =131.6dB, THD+N= -115dB.
- Sound quality design.
