用于便携式音响设备的低电压麦克风放大器

NJM2173是设计用于便携式音响设备的低电压麦克风放大器。它配有电池使用时电源波纹抑制用的端子，并实现了待机功能时的节能设计。另外，具有外部录音电平切换用的2档增益切换功能，故而实现了外接部件的消减，并使便携式音频设备更加容易使用。在增益切换时，实现了非常低的冲击噪声。本产品适用于便携式MD、便携式CD和其它麦克风放大器应用设备。 • 工作电压范围 (2.7到4.5V)\n• 消耗电流 (V+=2.7V时，一般为2.2mA)\n• 待机模式中的消耗电流 (最大为1μmA)\n• 最大输出电压 (THD=0.1%时，一般为-1.5dBV)\n• 内置增益切换功能 (一般为13dB／一般为29dB)\n• 内置待机功能\n• 电源纹波抑制端子 (Gv=13dB时，一般为95dB)\n• 双极技术\n• 封装 (SSOP14);
