For flagship models in the MUS-IC series, ROHM has developed a 32-bit D/A converter IC (DAC chip) and evaluation board that is tailored for high-resolution audio playback.
DAC chips are essential for assessing the quality of audio equipment since they are designed to extract and convert high-resolution sound data to analog as precisely as possible.
With products like high-fidelity sound processors and premium audio power ICs, ROHM has established exceptional sound quality design technology by utilizing its more than 50 years of experience in audio IC development.
The most recent innovation from ROHM expands upon the first generation MUS-IC BD34301EKV audio DAC chip, which is well-known for its superb sound quality and frequently seen in high-end models from different manufacturers.
In addition to incorporating the three components of spatial reverberation, quietness, and dynamic range from the MUS-IC series to accurately replicate the “texture” of musical instruments, the BD34302EKV carries over the fundamental design concept of ROHM’s DAC chip, which is natural flat sound, to provide an even more lifelike audio experience.
Through the implementation of a novel Data Weighted Averaging (DWA) algorithm, the BD34302EKV attains a THD+N characteristic of -117dB (THD: -127dB), a crucial performance metric that improves sound quality by producing a realistic texture.
Customers may fully utilize the high-precision computations of their digital signal processors (DSPs) with a sampling frequency of up to 1,536 kHz, while the signal-to-noise ratio (SNR) of 130 dB offers noise performance appropriate for a flagship DACchip.
Smoother, more natural sound is produced using ROHM’s exclusive HD (High Definition) monaural mode, which uses one DAC chip per channel. Unwavering craftsmanship has been applied to every aspect as part of the MUS-IC series.
The best bonding wire material for each terminal of the BD34302EKV was chosen based on years of experience in sound quality design in order to faithfully capture the inherent “texture” of musical instruments. These characteristics aid in producing the perfect sound that luxury audio producers are looking for.
