      CXAR41165是一款高效率,双声道全桥式驱动(BTL),具有耳机输出的D类音频放大器。在工作电压为5V时,CXAR41165每个通道可向4Ω负载连续输出2.8W的功率并具有10%的THD+N。CXAR41165其内部采用64阶音量控制电路,扬声器增益范围为-70dB 到 20dB,耳机增益范围为-80dB 到to 3.5dB。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。此外,AGC可以适应由电池供电电压降低引起的的输出clip。新型无滤波架构的采用使得CXAR41165可以直接驱动扬声器,从而降低了系统功耗和PCB面积。CXAR41165提供短路保护和过温保护,以避免芯片的损毁。CXAR41165采用24-pin SOP封装和20-pin 4×4 TQFN封装。The CXAR41165 is a high efficiency, 2 channel bridged-tied load (BTL), class-D audio power amplifier with headphone output. Operating from a 5V power supply, CXAR41165 is capable of delivering 2.8W/channel of continuous output power to a 4Ω load with 10% THD+N. The CXAR41165 features an advanced 64-step DC volume control which offers a range of speaker gain from -70dB to 20dB and a range of HP gain from -80dB to 3.5dB. The AGC detects output signal clip due to the over level input signal and suppresses it automatically. Moreover the AGC can adapt the output clip caused by power supply voltage down with battery. The new filter-less architecture allows the device to drive the speaker directly, without low-pass output filters, which will save system cost and PCB area. The CXAR41165 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The CXAR41165is available in 24-pin SOP and 20-pin 4×4 TQFN package.
