產(chǎn)品詳情ADM2582EBRWZ-REEL7
ADM2582E/ADM2587E驅(qū)動(dòng)器具有高電平有效使能特性。此外具有低電平有效接收器使能特性,禁用時(shí)可使接收器輸出進(jìn)入高阻態(tài)。
這些器件具有限流和熱關(guān)斷特性,可防止發(fā)生輸出短路以及總線(xiàn)競(jìng)爭(zhēng)導(dǎo)致功耗過(guò)大的情況。該器件的額定溫度范圍為工業(yè)溫度范圍,提供20引腳、寬體SOIC封裝。
ADM2582E/ADM2587E包含isoPower 技術(shù),應(yīng)用高頻率開(kāi)關(guān)元件通過(guò)變壓器實(shí)現(xiàn)轉(zhuǎn)換功率。設(shè)計(jì)印刷電路板(PCB)布局時(shí)應(yīng)特別小心,必須符合相關(guān)輻射標(biāo)準(zhǔn)。關(guān)于電路板布局考量因素的詳細(xì)信息,請(qǐng)參考應(yīng)用筆記AN-0971:isoPower 器件的輻射控制。
ADM2582E/ADM2587E是具備±15 kV ESD保護(hù)功能的完全集成式信號(hào)和電源隔離數(shù)據(jù)收發(fā)器,適合多點(diǎn)傳輸線(xiàn)路上的高速通信應(yīng)用。內(nèi)部集成隔離式DC-DC電源,無(wú)需外加DC-DC隔離模塊。
器件針對(duì)平衡傳輸線(xiàn)路而設(shè)計(jì),符合ANS/TIA/EIA-485-A-98和ISO 8482:1987(E)標(biāo)準(zhǔn)。
這些器件集成ADI公司的iCoupler®技術(shù),將一個(gè)3通道隔離器、一個(gè)三態(tài)差分線(xiàn)路驅(qū)動(dòng)器、一個(gè)差分輸入接收器和ADI公司的isoPower DC/DC轉(zhuǎn)換器集成于單封裝中。它們采用5V或者3.3V單電源供電,實(shí)現(xiàn)完全集成的信號(hào)和電源隔離RS-485解決方案。
應(yīng)用
·隔離式RS-485/RS-422接口
·工業(yè)現(xiàn)場(chǎng)網(wǎng)絡(luò)
·多點(diǎn)數(shù)據(jù)傳輸系統(tǒng)
