产品概述 返回TOP
CXAR41163是一款高效率，2通道全桥式驱动（BTL） D类音频功率放大器，在负载为6Ω或8Ω时驱动立体扬声器每个通道的功率为10W。CXAR41163采用全差分输入架构，相比于单端（SE）输入放大器具有更好的抗噪声能力。先进的EMI抑制技术与扩频控制只需在输出端使用廉价的磁珠便可以满足系统成本降低的电磁兼容（EMC）的要求。CXAR41163可以充分防止短路和过载，并且具有可调的功率限制电路和直流检测电路也保护所连接的扬声器。直流检测，引脚到引脚，引脚到地和引脚到电源的短路保护电路使扬声器免受生产中造成的输出直流和引脚短路。CXAR41163采用良好散热的28-pin TSSOP封装，在两层印刷电路板上可以实现全功率输出。The CXAR41163 is a high efficiency 2 channel bridged-tied load (BTL) Class-D audio power amplifier, driving stereo speakers at up to 10W/CH with 6Ω or 8Ω Load. The CXAR41163 features a differential input architecture offering improved noise immunity over a single-ended (SE) input amplifier. Advanced EMI Suppression Technology with Spread Spectrum Control enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements for system cost reduction. CXAR41163is not only fully protected against shorts and overload, an adjustable power limiter and a DC detection circuit for protection of the connected speakers. The DC detect and Pin-to-Pin, Pin-to-Ground and Pin-to-Power Short Circuit protection circuit protect the speakers from output DC and pin shorts caused in production. The short circuit protection and thermal protection includes an auto recovery feature. CXAR41163is available in thermally efficient 28-pin TSSOP package and will be able to output full power on a 2-layer PCB.
