DG2727DN-T1-E4集成電路（IC）的模擬開(kāi)關(guān)多路復(fù)用器解復(fù)用器規(guī)格書(shū)PDF中文資料

DG2727DN-T1-E4屬于集成電路（IC）的模擬開(kāi)關(guān)多路復(fù)用器解復(fù)用器。由威世科技半導(dǎo)體制造生產(chǎn)的DG2727DN-T1-E4模擬開(kāi)關(guān)，多路復(fù)用器，解復(fù)用器該系列產(chǎn)品可用于在多個(gè)可用信號(hào)路徑之間互連或路由模擬信號(hào)。功能類(lèi)似于傳統(tǒng)的機(jī)電開(kāi)關(guān)，但與機(jī)電開(kāi)關(guān)相比，它們的固態(tài)特性有利于電子控制、延長(zhǎng)使用壽命及降低開(kāi)關(guān)噪聲，但作為代價(jià)，切換信號(hào)的幅度和偏壓限制有所增加。

DESCRIPTION

The DG2727, DG2728, and DG2729 are 0.6 Ω dual SPST analog switches. When Sx are used as signal input, these devices support AC-coupled audio signals with single rail power supply. Audio signals can swing below ground down to V+ - 4.3 V.
