       CXAR41173B 为一款高效率，2通道全桥式驱动（BTL）D类音频放大器。在工作电压为16V，输出负载为8Ω的扬声器上，每个通道可以输送出15W/10%的输出功率及失真度。CXAR41173B其内部采用全差动输入设计，比起单端输入更能有效抑制噪声。利用G0和G1连个引脚，可以选择增益为20，26，32或是36dB。改进的EMI抑制技术使得在输出端可以使用廉价的铁氧体磁珠同时满足电磁兼容性要求。CXAR41173B内置扬声器保护电路，以限制流过扬声器的电流值。同时AGC可以检测出由于输入信号过大而引起的输出信号clip并自动抑制clip。CXAR41173B提供短路保护和过热保护，以避免芯片的损毁。CXAR41173B采用28-pin TSSOP封装。The CXAR41173B is a high efficiency, 2 channel bridged-tied load (BTL), class-D audio power amplifier. Operating from a 16V power supply, CXAR41173B is capable of delivering 15W/ channel of continuous output power to a 8Ω load with 10% THD+N. The CXAR41173B 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 20, 26, 32 or 36dB utilizing the G0 and G1 gain select pins. Advanced EMI suppression technology enables the use of inexpensive ferrite bead at the outputs while meeting EMC requirements. The speaker protection circuitry is integrated into CXAR41173B to limit the amount of current through the speaker. Meanwhile, the AGC detects output signal clip due to the over level input signal and suppresses it automatically. The CXAR41173 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The CXAR41173 is available in thermally efficient 28-pin TSSOP package.
