DG509ADY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG509ADY+ is a monolithic CMOS analog multiplexer featuring four differential channels (2-of-8 configuration) in a 16-pin Narrow SO package. It operates from dual supplies ranging from ±4.5V to ±18V with a typical supply current of 0.2mA at ±15V. The device guarantees break-before-make switching and latchup-proof construction. Drain-source on-resistance is specified at a maximum of 550Ω across the operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Monolithic CMOS design ensuring latchup-proof operation even when power supplies are off while input signals remain present
• Guaranteed break-before-make switching intervals to prevent signal shorting during channel transitions
• Symmetrical, bidirectional signal path capability supporting both multiplexing and demultiplexing applications

Analog Switches, Multiplexers, Demultiplexers Applications

• Data-acquisition systems requiring reliable signal routing
• Control systems utilizing sequential data processing
• Aircraft heads-up displays for instrument signal management
• Signal routing within complex instrumentation setups

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix 'DY+' corresponds specifically to the Narrow SOIC-16 package variant. Confirm the component meets lead-free and RoHS compliance standards as indicated by the plus sign. Ensure the procurement documentation explicitly references the Analog Devices or Maxim Integrated manufacturer source to guarantee authenticity and traceability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model over the DG508A when differential signal handling is required, as it provides two independent 4-channel paths rather than a single 8-channel path. Verify that the system voltage requirements fall within the ±4.5V to ±18V operational range. Consider the Narrow SO package constraints regarding thermal dissipation and board space availability compared to wider packages.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG508A/DG509A series of monolithic CMOS analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. The series serves as an industry-standard upgrade offering improved switching speeds and lower leakage currents compared to legacy equivalents. The DG509A variant specifically addresses differential signal routing needs within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed direct substitutes include other DG509A variants such as DG509ADJ+, DG509AEWE+, and DG509ABK+. These alternatives share identical electrical characteristics but differ in package type or temperature rating. Verify pin compatibility and thermal derating requirements before substitution.
