The ADG5408/ADG5409 are monolithic CMOS analog multiplexers comprising eight single channels and four differential channels, respectively. The ADG5408 switches one of eight inputs to a common output, as determined by the 3-bit binary address lines, A0, A1, and A2. The ADG5409 switches one of four differential inputs to a common differential output, as determined by the 2-bit binary address lines, A0 and A1. An EN input on both devices enables or disables the device. When EN is disabled, all channels switch off. The on-resistance profile is very flat over the full analog input range, which ensures good linearity and low distortion when switching audio signals. High switching speed also makes the parts suitable for video signal switching. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the power supplies. In the off condition, signal levels up to the supplies are blocked. The ADG5408/ADG5409 do not have VL pins; rather, the logic power supply is generated internally by an on-chip voltage generator.

產(chǎn)品詳情

ADG5408/ADG5409均為單芯片CMOS模擬多路復(fù)用器，分別內(nèi)置8個(gè)單通道和4個(gè)差分通道。ADG5408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。ADG5409根據(jù)2位二進(jìn)制地址線A0和A1所確定的地址，將4路差分輸入之一切換至公共差分輸出。

兩款器件均提供EN輸入，用來(lái)使能或禁用器件。EN禁用時(shí)，所有通道均關(guān)斷。導(dǎo)通電阻曲線在整個(gè)模擬輸入范圍都非常平坦，可確保開(kāi)關(guān)音頻信號(hào)時(shí)擁有良好的線性度和低失真性能。同時(shí)高開(kāi)關(guān)速度使這些器件適合視頻信號(hào)切換應(yīng)用。

當(dāng)接通時(shí)，各開(kāi)關(guān)在兩個(gè)方向的導(dǎo)電性能相同，輸入信號(hào)范圍可擴(kuò)展至電源電壓范圍。在斷開(kāi)條件下，達(dá)到電源電壓的信號(hào)電平被阻止。

ADG5408/ADG5409沒(méi)有VL引腳；相反，邏輯電源由片內(nèi)電壓發(fā)生器在內(nèi)部產(chǎn)生。
