产品描述

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.

模拟开关主要是完成信号链路中的信号切换功能。采用MOS管的开关方式实现了对信号链路关断或者打开；由于其功能类似于开关，而用模拟器件的特性实现，成为模拟开关。

       模拟开关在电子设备中主要起接通信号或断开信号的作用。由于模拟开关具有功耗低、速度快、无机械触点、体积小和使用寿命长等特点，因而，在自动控制系统和计算机中得到了广泛应用。
