80mW、固定增益、DirectDrive立體聲耳機放大器，帶有關斷

MAX4411固定增益、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備而設計的。MAX4411采用獨特的DirectDrive?結構，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，并降低了元件高度。此外，放大器增益在內部設定(MAX4411為-1.5V/V，MAX4411B為-2V/V)，進一步減少了元件數(shù)量。\n MAX4411每個通道可向16Ω負載輸出80mW，THD+N僅為0.003%。217Hz時86dB的高電源抑制比(PSRR)使該器件可以在沒有附加線性調節(jié)器的情況下，在充滿噪聲的數(shù)字電源下工作。MAX4411的耳機輸出端具有± \n? 無需笨重的隔直電容 \n? 固定的-1.5V/V增益省去外部反饋網(wǎng)絡 \n? MAX4411：-1.5V/V \n? MAX4411B：-2V/V \n? 以地為參考的輸出免除了向耳機接地引腳施加直流偏壓 \n? 避免了輸出電容造成的低頻響應損失 \n? 每個通道輸出80mW給16Ω負載 \n? THD+N僅0.003% \n? 高PSRR (217Hz時86dB) \n? 集成咔嗒/噼噗抑制電路 \n? 工作在1.8V至3.6V單電源下 \n? 低靜態(tài)電流(5mA) \n? 獨立的左/右聲道低功率關斷控制 \n? 短路保護與熱過載保護 \n? 放大器輸出端具有±8kV ESD;
