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
