高性能8通道模擬多路復(fù)用器，具有故障保護(hù)功能

ADG438F和ADG439F均為CMOS模擬多路復(fù)用器；ADG438F內(nèi)置8個(gè)單通道，ADG439F內(nèi)置4個(gè)差分通道，而且均可提供故障保護(hù)。這些器件采用串聯(lián)n溝道、p溝道和n溝道MOSFET結(jié)構(gòu)，發(fā)生過(guò)壓或失電時(shí)，器件與信號(hào)源均會(huì)受到保護(hù)。該多路復(fù)用器可以承受-40 V至+55 V的連續(xù)過(guò)壓輸入。在故障條件下，當(dāng)電源關(guān)閉時(shí)，多路復(fù)用器輸入（或輸出）表現(xiàn)為開(kāi)路，泄漏電流只有幾nA。這樣，不但可以保護(hù)多路復(fù)用器及其所驅(qū)動(dòng)的電路，而且可以保護(hù)驅(qū)動(dòng)多路復(fù)用器的傳感器或信號(hào)源。\n\n ADG438F根據(jù)3位二進(jìn)制地址線A0、A1和A2所確定的地址，將8路輸入之一切換至公共輸出。ADG439 ? 電源關(guān)閉時(shí)所有開(kāi)關(guān)斷開(kāi)\n\n? 如果發(fā)生過(guò)壓，接通通道的模擬輸出將箝位在電源電壓范圍內(nèi)\n\n? 無(wú)閂鎖設(shè)計(jì);
