DG509ADY-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG509ADY-T is a dual SP4T analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two independent multiplexer circuits, each configured as a 4-to-1 switch. The device utilizes a 16-CDIP package for through-hole mounting. It operates with dual power supplies ranging from ±4.5V to ±18V or a single supply of 4.5V to 36V. Key electrical characteristics include a maximum on-resistance of 450 ohms and a channel-to-channel matching of 27 ohms. Switching times are specified at a maximum of 1.5µs for turn-on and 1µs for turn-off. The component supports an operating temperature range from -20°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DY-T' against official manufacturer documentation to confirm tape-and-reel availability and exact pinout configuration. Cross-reference the part number with Analog Devices or Maxim Integrated databases to ensure compliance with current RoHS directives and material declarations. Confirm that the 16-CDIP package dimensions match the target footprint requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4-to-1 switching functionality is required within a single package. Ensure the application voltage does not exceed the ±18V dual supply limit. Verify that the 450-ohm on-resistance meets the signal integrity requirements of the connected circuitry. Consider the through-hole mounting style if surface area constraints allow for larger footprints compared to SOIC alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG509 family of analog switches, which are designed for general-purpose signal switching applications.
