How a High-Resolution D/A Converter Can Help Capture the Sound Quality of a Symphony Orchestra :The new BD34301EKV, a 32 bit D/A converter IC designed for high fidelity audio equipment
Since the invention of the phonograph, musicians and engineers alike have combined their talents in order to capture the dynamic range of musical instruments and translate them seamlessly into a format to be recorded and replayed. This, however, comes with major challenges (even in the 21st century) where optimizing digital signal quality parameters such as sampling rate, resolution, signal-to-noise ratio (SNR), and total harmonic distortion plus noise (THD + N) requires close attention in all stages of production from circuit design to wafer fabrication and packaging. Since the 1970s, ROHM has been steadily developing audio ICs, optimizing devices with a low distortion and high resolution to adequately capture and reproduce the sound image (effects), timbre (natural sound without coloring), and low-noise characteristics of acoustic instruments in the ambient experience of a concert hall. This whitepaper dives into the qualities and features of ROHMs latest musical IC ― the MUS-IC™ BD34301EKV, a high-resolution audio digital-to-analog converter (DAC). This component, along with an array of others (including a high-fidelity power supply and sound processor), offers the basic building blocks of a Hi-Fi audio device.
