具有可变压缩特性和噪声门的完整麦克风调理器

SSM2166是一款完整、灵活的集成解决方案，用于调理计算机音频系统中的麦克风输入。 在改善通信和公共广播系统的声音清晰度方面，它同样表现出色。 增益由一个低噪声、电压控制放大器(VCA)提供，并可通过控制环路进行动态调整，以维持设定的压缩特性。 压缩比由单个电阻设置，可相对于用户定义的旋转点在1:1至15:1以上的范围内变化；高于旋转点的信号会受到限制，以防止过载并消除爆音。 当压缩比设置为1:1时，SSM2166可通过编程将固定增益设置为最高20 dB；在其它压缩比设置情况下，还要再加上可变增益。 输入缓冲器的前端增益也可以配置为0 dB至20 dB。 向下扩展器（噪声门）可防止放大噪声或 • 完整的麦克风调理器， \n采用14引脚封装\n\n• 5 V单电源供电\n\n• 可调噪声门阈值\n\n• 压缩比由外部电阻设置;
