DG2751集成電路（IC）的模擬開關(guān)多路復(fù)用器解復(fù)用器規(guī)格書PDF中文資料

DG2751屬于集成電路（IC）的模擬開關(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DG2751模擬開關(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(guān)，但與機電開關(guān)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(guān)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 DG2751 is a compact, low resistance, ultra-low

distortion double pole double throw (DPST) analog switch.

The DG2751 features a flat 0.39 ? ON resistance over the

analog signal range from (V+) - 5.5 V to V+, supporting

bi-directional negative signal swing. The design brings

superior signal fidelity by eliminating the distortion caused

by double hump switch resistance character of conventional

analog switches.

The DG2751 operates over a voltage range from 3 V to

5.5 V. Because of its low current consumption, it can be

powered directly by a GPIO. When V+ power is off, all switch

pins are of high impedance mode.

Shunt switches are integrated at normally close (NOn)

channels to discharge the AC-coupling capacitance at the

terminals.

The part is controlled by a single bit, S, which can interface

with 1.2 V low voltage I/O. Switch ON/OFF is of

break-before-make (BBM).

The DG2751 is available in ultra-compact 1.2 mm x 1.2 mm,

9-bump WCSP package, and operate over the -40 °C to

+85 °C extended temperature range.

? Low parasitic capacitance

? Low voltage control interface
