HT3286-免电感滤波2×30W D类立体声音频功放
HT3286 is a stereo efficient, Class-D audio amplifier for driving
speakers up to 50W/4 Ω in mono PBTL. It can also deliver
2×33W/8Ω power in stereo BTL.
Advanced EMI Suppression with Spread Spectrum Control
enables the use of inexpensive ferrite bead filters while meeting
EMC requirements for system cost reduction.
HT3286 is fully protected against faults with Overvoltage,
Undervoltage, Overtemperature, DC-detect, and Overcurrent
protection. Faults can be reported to the processor to prevent
devices from being damaged.
HT3286是一款高效D类音频功率放大器。
在22V供电的立体声（BTL）模式、THD+N=10%条件下，能够持续提供2*33W/8Ω功率输出；在
单声道（PBTL）、模式、THD+N=1%条件下，
能够持续提供50W/4Ω功率输出。 HT3286具有先进的扩频功能来抑制EMI，
使用价格低廉且小体积铁氧体磁珠可满足EMC要求。 此外，HT3286内置关断功能使待机电流
最小化，还集成了过压保护、直流保护、短路
保护、热保护和电源欠压异常保护等功能，可
全面防止出现故障。
