60mW、DirectDrive、立體聲耳機(jī)放大器，具有較低的RF干擾敏感度，帶關(guān)斷控制

MAX9724A/MAX9724B立體聲耳機(jī)放大器是專為那些電路板空間很有限的便攜式設(shè)備而設(shè)計(jì)的。這些器件采用獨(dú)特的DirectDrive?架構(gòu)，可在單電源供電時(shí)產(chǎn)生以地為參考的輸出，無需大容量隔直電容，節(jié)省了成本，縮小了電路板空間，并降低了元件高度。MAX9724可以抑制由輸入和電源跡線的天線效應(yīng)引入的RF輻射，避免放大器不會(huì)對(duì)耦合進(jìn)來的噪聲進(jìn)行解調(diào)。MAX9724A提供外部可調(diào)增益，而MAX9724B則具有-1.5V/V的內(nèi)部預(yù)置增益。MAX9724A/MAX9724B每通道可向32Ω負(fù)載提供60mW功率，THD+N僅為0.02%。1kHz時(shí)高達(dá)80dB的電源抑制比(PSRR)使該 \n? 提高RF噪聲抑制(高達(dá)67dB，遠(yuǎn)遠(yuǎn)優(yōu)于典型放大器) \n? 無需大容量隔直電容 \n? 低功耗關(guān)斷模式，< 0.1μA \n? 可調(diào)增益(MAX9724A)或-1.5V/V的固定增益(MAX9724B) \n? 0.02%的THD+N \n? 高PSRR (1kHz時(shí)80dB)，無需LDO \n? 內(nèi)部集成有咔嗒-噼噗聲抑制電路 \n? 采用2.7V至5.5V單電源供電 \n? 低靜態(tài)電流(3.5mA) \n? 提供節(jié)省空間的封裝 \n? 12焊球UCSP封裝(1.5mm x 2mm) \n? 12引腳薄型QFN封裝(3mm x 3mm x 0.8mm);
