ROHM lancererer high-end 32-bit audio D/A-konverter

ROHM har som del af den såkaldte MUS-IC familie præsenteret BD34301EKV, der er en 32-bit audio D/A-konverter med tilhørende evalueringsboard, som sigter mod det mest krævende Hi-Fi udstyr (in english).

ROHM announces the new BD34301EKV, a 32bit D/A converter IC designed for high fidelity audio equipment – capable of high-resolution playback of audio sources. At the same time, ROHM also provides BD34301EKV-EVK-001 evaluation boards to test the performance of ROHM’s new IC that is sold via distributor channels.

Designed to maximally extract and convert high resolution audio data to analog, audio DAC chips are one of the most important components for determining the quality in audio equipment. Leveraging 50 years of expertise in developing audio ICs, it allowed ROHM to establish ‘sound quality design technology’ capable of extracting the full amount of information from sound sources and offer products that deliver superior sound quality, including sound processor and power management ICs.

The BD34301EKV DAC chip, developed as part of ROHM’s high-grade MUS-IC series representing the pinnacle of audio ICs, emphasizes 'spatial resonance', 'sense of scale' and 'quietness', which are qualities important for reproducing classical music.

Original sound quality design technology makes it possible to successfully reproduce the target sound quality by incorporating a circuit in the signal processing block to check audio quality. At the same time, class-leading low noise and distortion (130dB SN ratio, -115dB THD+N) provide the high performance demanded by high fidelity audio equipment. At last, the customizable digital filter – a key function of the digital signal processing circuit – supports the creation of the ideal sound sought by audio equipment manufacturers.
The BD34301EKV has been adopted in the digital circuit block of the flagship SACD/CD player D-10X from LUXMAN CORPORATION, a renowned manufacturer of high-end audio equipment.

Masakazu Nagatsuma, Director and General Manager of the Development department at LUXMAN, praised the performance and sound quality of the BD34301EKV from the development stage:
- The sound is natural and flat in all bands, making it easy to listen for extended periods of time.

BD34301EKV and evaluationboard is available through Digi-key, Mouser, and Farnell
