2.1W、防破音、D类、双声道功率放大器

HT2144是一种数字音频功率放大器，最大输出功率为2.1W（RL=4Ω）X 2ch。\r\n\r\nHT2144内部采用纯脉冲扬声器驱动电路，可减小输出信号失真，并减小信号噪声，实现了同类产品中高标准的低失真率和低噪音的性能。\r\n\r\n此外，电路采用新型调制技术，输出无需滤波网络，简化了系统设计和降低系统成本。\r\n\r\nHT2144实现了无削顶输出控制功能，可检测到由于输入幅度过大引起的输出信号削顶并自动衰减。此外，无削顶控制功能还可以检测到电源电压下降造成的输出削顶。这是区别传统的AGC（自动增益控制）或ALC（自动电平控制）电路。跟踪时间和释放时间可通过外部电阻或电容自由设定 • 最大输出功率\r\n• 总谐波失真（THD+N）\r\n• 噪声\r\n• 效率\r\n• 信噪比SNR\r\n• 通道隔离度\r\n• 过流保护\r\n• 过温保护\r\n• 欠压保护\r\n• 独立声道关断\r\n• 上电快速恢复\r\n• 封装\r\n\r\n Lead-free 16-pin WLCSP\r\n\r\n Lead-free 20-pin QFN\r\n\r\n Lead-free 20-pin TSSOP;
