D类音频放大器解决方案

更低温、更小且更轻的 D 类放大器，成就出色的音响音频产品

凭借革命性的多级 D 类放大器 IC，英飞凌在功率效率和功率密度方面都遥遥领先。倾听，感受，体验，皆为成就清晰音色。为确保呈现音频放大器性能，英飞凌 MERUS™ 产品的开发基于三大基本原则。

功率效率 —— 在扬声器中发声，而非加热周围环境

集成 —— 只闻其声，不见其形。褪去笨重身形，迎来纤巧新生

质量 —— 坚固灵活，而非易损苛求

英飞凌产品系列包含了完全集成单芯片音频解决方案，以及采用了高扩展度放大器驱动 IC 的分立式音频解决方案，并与功率 MOSFET 相结合。MERUS™ 作为英飞凌 D 类音频应用的专用产品系列，输出功率范围为每通道 20 W 至 2 kW，可满足各类设计要求。

随着单件产品音频通道数量的日益增加，紧凑型应用中的常规 D 类放大器面临着诸多挑战：低功率效率，过度产热（即使是在中等音量下），并且需要笨重、昂贵的滤波器。全球首创，英飞凌多级放大技术在改善功耗的同时降低电磁干扰和带外噪音。通过消除或尽量减少过滤器的使用，还可以降低制造成本，有助于节省设计空间。

Consumers today are placing increasing importance to excellent sound quality in audio devices. Particularly, for home sound systems and equipment, superior sound adds a great atmosphere to any setting. Meeting modern demands of audio applications, MERUS™ class D amplifiers maximize audio performance and battery playback time for smart home and battery-powered speakers while minimizing heat and design space.
