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.

TPA6011A4EVM — TPA6011A4 評估模組 (EVM)

TPA6011A4 是一款立體聲音訊功率放大器,可在 3Ohm 喇叭上輸出每通道 2W 的持續 RMS 功率。

筆記型電腦與掌上型電腦可受益於其整合的功能組合,這些功能在不犧牲效能的情況下,將外部元件需求降至最低。為簡化設計,喇叭音量可透過在音量終端施加直流電壓來調整。同樣地,喇叭音量與耳機音量之間的差值,可透過在 SEDIFF 終端施加直流電壓來調整。為避免耳機出現意外的高音量,第三個終端 SEMAX 可在施加直流電壓時限制耳機音量。最後,為確保在工作模式與關閉模式之間平順切換,淡入/淡出模式可讓音量漸進式地提升與降低。
