Key Features
1．Achieves high-fidelity audio by introducing sound quality design technology that optimizes proprietary parameters
The BD34602FS-M integrates newly developed original audio quality technology. Extracting the full data from audio sources by optimizing 28 unique parameters centered on circuit configuration and electrical characteristics that have been shown to have an effect on IC sound quality enables accurate spatial representation (perceived distance and location of sound source), and as a result has been well-received by car audio manufacturers.
- Incorporates key audio characteristics
- Reduces IC midpoint bias-circuit noise by approx. 20%
- Decreases noise generated low-frequency noise generated in the volume circuit by up to 10x
- Improving resolution (sound clarity) and spatial representation (perceived location and distance from sound) along with transient characteristics by adopting a layout that suppresses signal interference makes it possible to extract the full data from audio sources
2．Provides industry-leading audio performance
Leveraging expertise cultivated over many years and analog design technology in areas that cannot be reproduced in simulations allowed ROHM to develop automotive sound processors that achieve an industry-low 0.0004% distortion and floor noise of 3.1uVrms during volume attenuation.
3．Built-in mixing circuit integrates original popping-noise reduction technology
An interrupt function (mixing) for both voice-navigation and hands-free modes is built in. Generally, when turning mixing ON/OFF unwanted popping-noise may occur, but with ROHM’s original advanced switching technology these popping noises are minimized.
Product Specifications
*1: Variable volume gain between -79dB and +23dB and -∞ reduces popping noise
*2: Minimizes popping noise during mixing ON/OFF
