DG509ACWE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG509ACWE+T is a monolithic CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features two differential 4-channel (2-of-8) switching configurations within a single package. The device supports dual power supplies ranging from ±4.5V to ±18V and operates within an industrial temperature range of 0°C to +70°C. It utilizes a 28-pin Wide SOIC surface-mount package. Key electrical characteristics include break-before-make switching action, guaranteed latch-up immunity during power-off conditions with active input signals, and low charge injection for signal integrity.
