DG403DY

Dual SPDT High-Speed Monolithic CMOS Analog Switch manufactured by Siliconix (Vishay / Analog Devices). This high-performance linear integrated circuit integrates two independent Single-Pole/Double-Throw (SPDT) switches (containing two normally open and two normally closed logic paths) inside a 16-pin small-outline (SOIC-16) package. It functions by providing low on-resistance (<45 Ω) and fast switching thresholds (\(t_{ON} < 150\text{ ns}\)) while handling dual-rail split supplies from ±4.5 V to ±20 V or single positive voltage loops up to +30 V. It is prominently engineered into high-accuracy sample-and-hold circuit nodes, professional multi-channel audio mixing consoles, automated test equipment (ATE) switching arrays, and battery-powered telemetry hardware.
