描述 Description

General Description
The DG201A and DG211 are normally closed, quad single-pole single-throw (SPST) analog switches. These CMOS switches can be continuously operated with power supplies ranging from ±4.5V to ±18V. Maxim guarantees that these switches will not latch up if the power supplies are disconnected with input signals still connected.
Both devices have guaranteed break-before-make switching. The DG201A differs from the DG211 primarily in switching speeds. The DG201A has a maximum turn-off time of 450ns and a maximum turn-on time of 600ns. The DG211 has a maximum turn-off time of 500ns and a maximum turn-on time of 1000ns. Compared to the original manufacturer’s products, Maxim’s DG201A and DG211 consume significantly lower power making them better suited for portable applications. Maxim has also eliminated the need for the third (VL) power supply that is required for the operation of the original manufacturer’s DG211.

简介

DG201属于集成电路（IC）的模拟开关多路复用器解复用器。由制造生产的DG201模拟开关，多路复用器，解复用器该系列产品可用于在多个可用信号路径之间互连或路由模拟信号。功能类似于传统的机电开关，但与机电开关相比，它们的固态特性有利于电子控制、延长使用寿命及降低开关噪声，但作为代价，切换信号的幅度和偏压限制有所增加。
