New DAC chip lineup for high-end audio

02-03-2022 | ROHM Semiconductor | Semiconductors

ROHM has developed the D/A converter IC (DAC chip) BD34352EKV and the corresponding evaluation board BD34352EKV-EVK-001 to support the playback of high-resolution sound sources in high fidelity audio equipment.


Created to maximally extract and convert high-resolution digital audio data to analog audio signals, audio DAC chips are one of the most important components for defining the quality in audio equipment.


Among these is the BD34301EKV, the flagship DAC chip of the company's MUS-IC series, highly evaluated for its sound quality since its release. However, to satisfy the increasing demand from manufacturers for a DAC chip that can be employed in a broader range of audio equipment, it has developed the BD34352EKV.


The new DAC chip BD34352EKV is specifically tuned to express the energy of sound sources while preserving the natural flat sound characteristics of its DAC chips design concept. At the same time, an advanced digital filter is incorporated - the same as for BD34301EKV. That leads to the DAC chip's excellent numerical performance (S/N ratio: 126dB, THD+N: -112dB), making it ideal for high-end audio equipment. Also, the BD34352EKV offers pin compatibility with the BD34301EKV. It has the same customisable filter as the BD34301EKV. This allows different sound quality tunings for every audio device – easing development load while contributing to developing the ideal sound sought by audio manufacturers.
