SGM2268数据手册SGMICRO中文资料规格书

描述 Description

The SGM2268 is a dual SPDT (single-pole/double-throw) analog switch. It operates from a 1.8V to 4.2V single power supply.
The SGM2268 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, audio and video signal routing, etc. In addition, the SGM2268 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 SGM2268 is available in a Green TQFN-1.8×1.4-10L package. It operates over an ambient temperature range of -40℃ to +85℃.
