DG409DY-TUBE Dual 4-Channel Differential Multiplexer

DG409DY-TUBE is built for multiplexing differential signals in data acquisition, test equipment, and control systems. It’s a dual 4-channel differential analog multiplexer that connects one of four differential inputs to a common dual output, selected by a 2-bit address. Break-before-make switching action helps protect against momentary crosstalk between adjacent channels during transitions. DG409DY-TUBE also supports flexible supply options: the datasheet notes operation from a +5 V to +30 V single supply and from ±5 V to ±20 V dual supplies. Use DG409DY-TUBE when you want one device to handle differential channel selection without adding separate switch networks. Keep the control lines clean to avoid unintended address changes during sampling. Request a quote for DG409DY-TUBE.
