三通道音频放大器

 SD7402是一款三通道音频放大器，内置麦克风输入放大电路，音频放大器和麦克风放大器的增益可灵活地通过外接电阻进行调节。典型条件下，音频输出信噪比100dB，总谐波失真0.01%，通道隔离度84dB。它采用BICMOS工艺，内置稳压模块，可安全稳定地工作在+5V/-12V系统中；内置的滤波电路对音频以外的信号进行衰减处理，可进一步提高信号质量；具有静音及POP声抑制功能，通过简单地联结外围器件，能够将开关机时输入信号的POP声进行抑制。它可广泛地应用于各种立体声或2.1声道音响系统中，对来自主芯片DAC等音源的信号进行前置放大处理。 ·BICMOS工艺 \n·双电源工作（+5V/-12V） \n·内置稳压模块 \n·失真度低 \n·待机功能 \n·静音及开关机POP声抑制功能;
