SGM3718中文资料0.6Ω Ultra Low On-Resistance, Negative Signal Passing, Dual SPDT Analog Switch数据手册SGMICRO规格书

描述 Description

The SGM3718 is a dual SPDT (single-pole/double-throw) analog switch. It operates from a 2.5V to 5V single power supply and allows a -2V negative signal passing with low distortion. 
The SGM3718 features ultra-low on-resistance, low voltage and fast switching times. The high performances make it very suitable for multiple applications, such as portable equipment, battery-powered systems, etc. In addition, the SGM3718 can be used as a dual 2-to-1 multiplexer because it has two normally open and two normally close switches. Low power consumption is also one of the important reasons that make it a good choice. 
The SGM3718 is available in a Green UTQFN-1.8×1.4-10L package. It operates over an ambient temperature range of -40℃ to +85℃.
