DG413DY+

The DG413DY+ from Analog Devices is a quad single-pole single-throw (SPST) analog switch IC housed in a 16-lead SOIC package. Internally, the device integrates four independently controlled channels configured as two normally open and two normally closed switches. It is an improved evolution of earlier generations, offering a typical on-resistance of 45 Ω and low charge injection, which helps preserve signal integrity in precision designs. The switch architecture supports rail-to-rail analog signal handling with a wide supply voltage range, while logic inputs are TTL and CMOS compatible, simplifying interface with standard digital controllers. Guaranteed break-before-make switching action prevents momentary short circuits during state transitions, and the low power dissipation makes the part suitable for both single-supply and dual-supply operation.

This component finds use across industrial process controls, automated test equipment, data acquisition front-ends, and military/aerospace signal routing where reliable low-voltage analog multiplexing is required. The SOIC footprint delivers a balance of board density and ease of assembly in medium-volume production. For procurement considerations, the DG413DY+ is a commercial/industrial temperature-grade device; applications demanding extended reliability, radiation tolerance, or military screening should investigate the availability of high-reliability variants such as those offered with MIL-STD-883 processing. As a mature Analog Devices product, the family typically benefits from stable lifecycle management, but design engineers are advised to verify long-term supply status and alternative sourcing pathways when qualifying this device for systems with extended production lifetimes.
