具有AGC和低噪声麦克风偏置电路的麦克风放大器

MAX9814是一款低成本、高性能麦克风放大器，具有自动增益控制(AGC)和低噪声麦克风偏置。器件具有低噪声前端放大器、可变增益放大器(VGA)、输出放大器、麦克风偏置电压发生器和AGC控制电路。\n\n 低噪声前置放大器具有12dB固定增益；VGA增益根据输出电压和AGC门限在20dB至0dB间自动调节。输出放大器提供可选择的8dB、18dB和28dB增益。在未压缩的情况下，放大器的级联增益为40dB、50dB或60dB。输出放大器增益由一个三态数字输入编程。AGC门限由一个外部电阻分压器控制，动作/释放时间由单个电容编程。动作/释放时间比由一个三态数字输入设置。AGC保持时间固定 • 自动增益控制(AGC)\n• 3种增益设置(40dB、50dB、60dB)\n• 可编程动作时间\n• 可编程动作和释放时间比\n• 2.7V至5.5V电源电压范围\n• 低输入噪声密度30nV/\n• 低THD：0.04% (典型值)\n• 低功耗关断模式\n• 内置2V低噪声麦克风偏置\n• 提供节省空间的14引脚TDFN (3mm x 3mm)封装\n• -40°C至+85°C扩展级温度范围;
