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(píng)估模塊 (EVM)

TPA6011A4 是一款立體聲音頻功放，可驅(qū)動(dòng) 3Ω 揚(yáng)聲器實(shí)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(shè)備在精簡(jiǎn)外圍元件的同時(shí)確保功能完整。為簡(jiǎn)化設(shè)計(jì)，揚(yáng)聲器音量可通過向 VOLUME 端子施加直流電壓進(jìn)行調(diào)節(jié)。與此同時(shí)，揚(yáng)聲器與耳機(jī)音量差值可通過向 SEDIFF 端子施加直流電壓進(jìn)行調(diào)節(jié)。為防止耳機(jī)意外高音量輸出，可通過向第三個(gè)端子，即 SEMAX 端子施加直流電壓時(shí)來限制耳機(jī)音量。此外，淡入淡出模式可確保工作/關(guān)機(jī)狀態(tài)平滑切換，實(shí)現(xiàn)音量漸變調(diào)節(jié)。
