產(chǎn)品描述

The SGM4717EP is a dual, bidirectional, single-pole/double-throw (SPDT) CMOS analog switch designed to operate from a single +1.8V to +5.5V supply. It features high-bandwidth (300MHz) and low on-resistance (4.5Ω TYP), targeted applications for audio switching.

SGM4717EP features guaranteed on-resistance matching (0.3Ω MAX) between switches and guaranteed on-resistance flatness over the signal range (2.3Ω TYP). This ensures excellent linearity and low distortion when switching audio signals.

The SGM4717EP is a committed dual single-pole/double-throw (SPDT) that consist of two normally open (NO) and two normally close (NC) switches. This configuration can be used as a dual 2-to-1 multiplexer.

SGM4717EP is available in Green TQFN-1.8×1.4-10L package.

模擬開關(guān)主要是完成信號(hào)鏈路中的信號(hào)切換功能。采用MOS管的開關(guān)方式實(shí)現(xiàn)了對(duì)信號(hào)鏈路關(guān)斷或者打開；由于其功能類似于開關(guān)，而用模擬器件的特性實(shí)現(xiàn)，成為模擬開關(guān)。

       模擬開關(guān)在電子設(shè)備中主要起接通信號(hào)或斷開信號(hào)的作用。由于模擬開關(guān)具有功耗低、速度快、無機(jī)械觸點(diǎn)、體積小和使用壽命長等特點(diǎn)，因而，在自動(dòng)控制系統(tǒng)和計(jì)算機(jī)中得到了廣泛應(yīng)用。
