GENERAL 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℃.
