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 評估模塊 (EVM)

TPA6011A4 是一款立體聲音頻功放,可驅動 3Ω 揚聲器實現(xiàn)每通道 2W 連續(xù) RMS 輸出。

憑借高度集成特性,可幫助筆記本與掌上設備在精簡外圍元件的同時確保功能完整。為簡化設計,揚聲器音量可通過向 VOLUME 端子施加直流電壓進行調(diào)節(jié)。與此同時,揚聲器與耳機音量差值可通過向 SEDIFF 端子施加直流電壓進行調(diào)節(jié)。為防止耳機意外高音量輸出,可通過向第三個端子,即 SEMAX 端子施加直流電壓時來限制耳機音量。此外,淡入淡出模式可確保工作/關機狀態(tài)平滑切換,實現(xiàn)音量漸變調(diào)節(jié)。
