CMOS, Low-Voltage, 3-Wire Serially-Controlled, Matrix Switches

GENERAL DESCRIPTION The ADG738 and ADG739 are CMOS analog matrix switches with a serially-controlled 3-wire interface. The ADG738 is an 8-channel matrix switch, while the ADG739 is a dual 4-channel matrix switch. On resistance is closely matched between switches and very flat over the full sign

2.5 Ω、低壓、三線式串行控制、雙路4通道矩陣開(kāi)關(guān)

ADG739是一款CMOS、雙路4通道模擬矩陣開(kāi)關(guān)，配有一個(gè)串行控制的三線式接口。開(kāi)關(guān)之間的導(dǎo)通電阻匹配嚴(yán)格，并且在整個(gè)信號(hào)范圍內(nèi)，導(dǎo)通電阻曲線非常平坦。 \n\n ADG739采用三線式串行接口，并且與SPI?、QSPI?、MICROWIRE?及一些DSP接口標(biāo)準(zhǔn)兼容。利用移位寄存器DOUT的輸出，可以將若干這種器件以菊花鏈形式相連。上電時(shí)，內(nèi)部移位寄存器為全零，所有開(kāi)關(guān)均處于斷開(kāi)狀態(tài)。\n\n 接通時(shí)，各開(kāi)關(guān)在兩個(gè)方向的導(dǎo)電性能相同，因此這種器件既適合多路復(fù)用，也適合解復(fù)用應(yīng)用。每個(gè)開(kāi)關(guān)均通過(guò)單獨(dú)的位接通或斷開(kāi)，因此這種器件也可以配置為開(kāi)關(guān)矩陣形式，八個(gè)開(kāi)關(guān)中的任意或所 ? 三線式串行接口\n\n? 2.7 V至5.5 V單電源供電\n\n? 導(dǎo)通電阻：2.5 Ω\n\n? 導(dǎo)通電阻平坦度：0.75 Ω;
