DG2727集成電路（IC）的模擬開關多路復用器解復用器規(guī)格書PDF中文資料

DG2727屬于集成電路（IC）的模擬開關多路復用器解復用器。由威世科技半導體制造生產(chǎn)的DG2727模擬開關，多路復用器，解復用器該系列產(chǎn)品可用于在多個可用信號路徑之間互連或路由模擬信號。功能類似于傳統(tǒng)的機電開關，但與機電開關相比，它們的固態(tài)特性有利于電子控制、延長使用壽命及降低開關噪聲，但作為代價，切換信號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.
