The TPA6011A4 is a stereo audio power amplifier that drives 3 W/channel of continuous RMS power into a 3- load. Advanced dc volume control minimizes external components and allows BTL (speaker) volume control and SE (headphone) volume control. Notebook and pocket PCs benefit from the integrated feature set that minimizes external components without sacrificing functionality.

To simplify design, the speaker volume level is adjusted by applying a dc voltage to the VOLUME terminal. Likewise, the delta between speaker volume and headphone volume can be adjusted by applying a dc voltage to the SEDIFF terminal. To avoid an unexpected high volume level through the headphones, a third terminal, SEMAX, limits the headphone volume level when a dc voltage is applied. Finally, to ensure a smooth transition between active and shutdown modes, a fade mode ramps the volume up and down.

评估板

TPA6011A4EVM — TPA6011A4 评估模块 (EVM)

TPA6011A4 是一款立体声音频功放，可驱动 3Ω 扬声器实现每通道 2W 连续 RMS 输出。

凭借高度集成特性，可帮助笔记本与掌上设备在精简外围元件的同时确保功能完整。为简化设计，扬声器音量可通过向 VOLUME 端子施加直流电压进行调节。与此同时，扬声器与耳机音量差值可通过向 SEDIFF 端子施加直流电压进行调节。为防止耳机意外高音量输出，可通过向第三个端子，即 SEMAX 端子施加直流电压时来限制耳机音量。此外，淡入淡出模式可确保工作/关机状态平滑切换，实现音量渐变调节。
