50mW、DirectDrive?、立體聲耳機(jī)放大器，帶有SmartSense?和關(guān)斷

MAX9720立體聲耳機(jī)放大器集成了Maxim的DirectDrive和SmartSense技術(shù)，可自動(dòng)檢測(cè)單聲道/立體聲模式。傳統(tǒng)的耳機(jī)放大器在耳機(jī)和放大器之間需要一個(gè)大尺寸的隔直電容。DirectDrive可以在單電源供電的情況下產(chǎn)生一個(gè)以地為基準(zhǔn)的輸出，無(wú)需大尺寸的隔直電容，可以節(jié)省成本、減小電路板空間和降低元件高度。\n SmartSense自動(dòng)探測(cè)左聲道或者右聲道運(yùn)放輸出的短路狀態(tài)。發(fā)生故障時(shí)，出現(xiàn)短路的輸出被自動(dòng)禁止，而立體聲輸入信號(hào)被自動(dòng)混合，并通過(guò)剩下的有效通道輸出。此功能在手機(jī)和PDA等應(yīng)用中非常有用，因?yàn)樵诖祟?lèi)應(yīng)用中，耳機(jī)插孔可能經(jīng)常有很多不同負(fù)載的耳機(jī)接入。SmartSe \n?
