3-W Stereo Audio Power Amplifier with Advanced DC Volume Control 数据表 
TPA6011A4是一款立体声音频功率放大器，可将3 W /通道的连续RMS功率驱动成3 加载。先进的直流音量控制可最大限度地减少外部组件，并允许BTL（扬声器）音量控制和SE（耳机）音量控制。笔记本电脑和掌上电脑受益于集成的功能集，可在不牺牲功能的情况下最大限度地减少外部元件。
为简化设计，通过向VOLUME端子施加直流电压来调节扬声器音量。同样，可以通过向SEDIFF端子施加直流电压来调节扬声器音量和耳机音量之间的差值。为避免通过耳机产生意外的高音量，第三个终端SEMAX在施加直流电压时限制耳机音量。最后，为了确保活动和关闭模式之间的平滑过渡，淡入淡出模式会上下调高音量。
