CXAR41172是一款高效率的单声道全桥式驱动D类音频放大器。当电源电压为12V时，CXAR41172 能在输出负载为8Ω的扬声器上，输送出6.5W / 10% 的输出功率及失真度。全差动输入设计比起单端输入更能有效抑制噪声。利用G0与G1两个接脚，可以选择增益为 12、18、23.6或是35.5dB。CXAR41172提供输出短路与过热保护，以避免芯片的损毁
• 工作电压：8 V至24 V
• 独特调变方案来减少EMI干扰
• 负载8Ω，工作电压12V时，输出可达6.5W (10% THD+N)
• 输出短路保护 (输出不需额外的两颗Schottky Diodes)
• 静态电流：8mA Typ at 12V
• 关断电流：1μA Typ
• 具散热垫 24-pin TSSOP包装

CXAR41172是一款高效率的单声道全桥式驱动D类音频放大器。当电源电压为12V时，CXAR41172 能在输出负载为8Ω的扬声器上，输送出6.5W / 10% 的输出功率及失真度。全差动输入设计比起单端输入更能有效抑制噪声。利用G0与G1两个接脚，可以选择增益为 12、18、23.6或是35.5dB。CXAR41172提供输出短路与过热保护，以避免芯片的损毁。 CXAR41172采用TSSOP封装，不需额外的散热垫。The CXAR41172 is a high efficiency, mono bridged-tied load (BTL), class-D audio power amplifier. Operating from a 12V power supply, CXAR41172 is capable of delivering 6.5W of continuous output power to a 8Ω load with 10% THD+N. The CXAR41172 features a differential input architecture offering improved noise immunity over a single-ended (SE) input amplifier. Amplifier gain is internally configured and can be selected to 12, 18, 23.6 or 35.5dB utilizing the Go and G1 gain select pins. The CXAR41172 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The CXAR41172 is available in thermally efficient 24-pin TSSOP package and does not require an external heat sink.
