ROHM has unveiled its second-generation MUS-IC™ BD34302EKV audio DAC chip, a flagship offering designed for high-resolution audio playback. This new chip continues ROHM’s tradition of delivering exceptional sound quality by incorporating a natural flat sound profile, enhanced with the unique qualities of spatial reverberation, quietness, and dynamic range. Building on over 50 years of audio IC development expertise, ROHM’s latest innovation is tailored to extract and convert high-resolution sound data into analog with unparalleled precision, catering to the stringent demands of high-end audio manufacturers.
The BD34302EKV DAC chip employs an advanced Data Weighted Averaging (DWA) algorithm, enabling an industry-leading Total Harmonic Distortion Plus Noise (THD+N) characteristic of -117dB and an impressive signal-to-noise ratio (SNR) of 130dB. These technical advancements ensure that the chip faithfully reproduces audio with remarkable clarity, capturing the intricate “texture” of musical instruments. Additionally, the chip supports an ultra-high sampling frequency of up to 1,536kHz, empowering digital signal processors (DSPs) to perform at their best. The inclusion of HD monaural mode further enhances the audio experience, delivering smoother, more natural sound by dedicating one DAC chip to each channel.
As part of the MUS-IC™ series, the BD34302EKV reflects ROHM’s meticulous craftsmanship and attention to detail. From its optimized bonding wire materials to its design philosophy rooted in preserving natural sound, the chip aims to set a new benchmark for audio quality. It inherits the legacy of its predecessor, the BD34301EKV, while pushing the boundaries of audio performance, making it a prime choice for high-end audio equipment. By combining cutting-edge technology with ROHM’s commitment to sound quality, the BD34302EKV redefines the standard for authentic and immersive audio playback.
