Overview
The DG509AEWE is a high-speed analog multiplexer manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a single 8:1 multiplexer circuit housed in a 16-SOIC package with surface-mount installation. The device supports dual supply voltages ranging from ±4.5V to ±18V and operates within a temperature range of -40°C to +85°C. Key electrical specifications include a maximum on-resistance of 450 ohms, a channel-to-channel matching of 27 ohms, and a typical on-resistance of 450 ohms. Switching times are specified at a maximum of 1.5µs for turn-on and 1µs for turn-off. Leakage current is limited to a maximum of 1nA, with off-state capacitance values of 5pF for source and 25pF for drain.

Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and REACH registration details prior to procurement. Ensure the specific suffix matches required packaging and environmental certifications. Cross-reference datasheet revisions to confirm pinout and electrical parameter consistency with existing designs.
Selection Notes
Select this component when an 8:1 analog switch topology is required with moderate on-resistance specifications. Evaluate the 450-ohm on-resistance against signal integrity requirements for the target application bandwidth. Consider the 16-SOIC package dimensions for PCB layout constraints. Verify that the ±4.5V to ±18V supply range aligns with available system power rails.
Part Context
The DG509AEWE belongs to the DG508/DG509 family of high-speed CMOS analog switches. This series is designed for applications demanding fast switching speeds and low distortion. The device utilizes iCMOS technology to achieve performance levels suitable for precision data acquisition and communication systems. It serves as a specialized interface component within broader power management and signal conditioning ecosystems.
Replacement Considerations
Direct substitutes may include other 8:1 analog multiplexers from the same manufacturer family. Verify pin compatibility and electrical parameter equivalence before substitution. Alternative packages such as TSSOP may require adapter solutions if footprint changes are permissible.
