在会议系统中，通常会用麦克风来采集音频信号，将音频信号转换为电信号再经过一系列的放大，混频处理，最后通过扬声器将声音扩散出来。由于在音频调试过程中非常容易出现噪声过大，失真严重等现象，因此许多工程师在会议系统设计中，也会将处理后的音频信号分为多路由调音台做一个辅助输出，经过终端处理后进行远程信号传输。

有客户在设计一款会议系统时，需要用到一款立体声线性驱动器，用来驱动扬声器，信号在差分输入单端输出后会连接一个音频功放对信号进行功率放大，音频驱动采用3.3V供电，要求频率在10KHz左右，具备低噪声，低功率特点。

本文给客户推荐圣邦微（SGMICRO）的2_VRMS自由立体声线路驱动器 SGM89000，能够以3.3V电源电压将2Vrms驱动至2.5KΩ负载，具有差分输入，内置开关控制，使用外部增益设置电阻，支持增益范围为±1V/V至±10V/V，非常适合用于音频设备线性驱动场合。会议系统应用框图如图1所示：

图1 会议系统框图

SGM89000在该会议系统中的优势：

1. SGM89000的供电电压为3.0V~3.6V，满足3.3V的电压需求；

2. 无电容音频驱动结构，能在20kHz的频率范围内提供平坦的频率响应，满足大于10KHz需求；

3. 静态电流典型值0.13mA，具备低功耗特点；

4. 低噪声和低THD，SNR典型值114dB，VN典型值5.5μVrms；
