5V、差分輸入、DirectDrive、130mW立體聲耳機放大器，帶有關(guān)斷

MAX9722A/MAX9722B立體聲耳機放大器是針對那些電路板空間很有限的便攜設(shè)備而設(shè)計的。MAX9722A/MAX9722B采用獨特的DirectDrive?結(jié)構(gòu)，在單電源供電下能產(chǎn)生以地為參考的輸出，從而省去了大容量隔直電容，節(jié)省了成本、電路板空間以及元件高度。此外，放大器的增益也由內(nèi)部設(shè)定(-2V/V、MAX9722B)，或外部調(diào)整(MAX9722A)。MAX9722A/MAX9722B每個通道可向16Ω負(fù)載輸出70mW，或向32Ω負(fù)載輸出130mW，THD+N僅為0.009%。217Hz時80dB的電源抑制比(PSRR)使該器件可以在沒有附加線性調(diào)節(jié)器的情況下，在嘈雜的數(shù)字 \n? 工作在2.4V至5.5V的單電源下 \n? 高PSRR (217Hz時80dB)無需LDO \n? 無需大容量隔直電容 \n? 以地為參考的輸出省去了耳機接地引腳的DC偏置電壓 \n? 不會因為輸出電容而使低頻響應(yīng)變差 \n? 差分輸入增強了噪聲抑制能力 \n? 可調(diào)增益(MAX9722A)或固定增益-2V/V (MAX9722B) \n? 每個通道輸出130mW給32Ω負(fù)載 \n? THD+N僅0.009% \n? 集成咔嗒聲/噼噗聲抑制 \n? 低靜態(tài)電流(5.5mA) \n? 短路和過熱保護(hù) \n? 放大器輸出端具有±8kV ESD保護(hù)(人體模型) \n? 采用節(jié)省空間的;
