差分麦克风前置放大器，内部偏置并可完全关断

MAX4063是一款专为高性能便携式应用优化设计的差分输入麦克风前置放大器。该器件具有两路可选输入、差分输出、可调增益、集成低噪声偏置源以及低功耗关断模式等特性。两个输入通道分别用于差分和单端麦克风输入。差分输入具有很高的噪声抑制能力，特别适合于内部麦克风，可有效避免系统噪声和PCB上的长线传输对于低电平信号的损伤。单端输入用于连接外部麦克风非常简便。\n\n 差分和单端输入具有独立、可调的增益，增益由一个外部电阻设定。差分输出使该器件工作于单一3V电源时能够提供6VP-P的满度输出信号，提供了最佳的放大信号动态范围。完全关断模式将电源电流降低至0.3µA，同时禁止掉麦克风偏置，最大 • 2.4V至5.5V单电源工作\n• 差分输入和输出\n• 可调增益\n• 高PSRR (95dB)\n• 高CMRR (79dB)\n• 集成低噪声麦克风偏置\n• 工作电流750µA\n• 关断电流0.3µA\n• ±4kV　ESD保护(AUX_IN)\n• THD+N：1kHz时0.05%\n• 提供节省空间的封装\n• 14引脚TSSOP封装\n• 16引脚薄型QFN封装(4mm x 4mm x 0.8mm);
