ADG509AKR-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG509AKR-REEL is a CMOS monolithic analog multiplexer featuring four differential channels. It switches one of four differential inputs to a common differential output based on two binary address lines (A0, A1) and an active-high enable input. The device operates within a wide supply range of 10.8 V to 16.5 V for both single and dual supplies. Key electrical specifications include a maximum on-resistance of 450 Ω at ±10 V supply, typical off-input leakage of 20 pA, and charge injection of 4 pC. Switching transition times are typically 200 ns with break-before-make timing guaranteed.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status. The REEL suffix indicates tape and reel packaging suitable for automated assembly. Confirm RoHS compliance requirements if applicable, as Z-suffixed variants are explicitly marked as RoHS compliant in the official guide. Ensure the selected variant matches the required temperature grade and pin configuration for the target PCB design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG509AKR-REEL when differential signal integrity is critical compared to single-ended alternatives like the ADG508A. This part is appropriate for designs requiring operation across wide supply voltages up to 16.5 V. Consider the 16-lead SOIC package dimensions for layout constraints. Verify that the digital interface voltage levels align with the TTL/CMOS compatible input thresholds specified in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG508A/ADG509A series of CMOS analog multiplexers manufactured by Analog Devices Inc. The series utilizes enhanced LC2MOS technology to provide robust performance over extended temperature ranges. The ADG509A variant specifically addresses differential signal paths, serving as a functional counterpart to the octal single-ended ADG508A within the same product family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public documentation identifies the DG509A and HI-509 as prior generation or alternative devices within the same functional class. Designers should verify pin compatibility and electrical parameter differences before substitution. No other direct public substitutes are confirmed in the provided source material.
