DG418LDY+

Overview

The DG418LDY+ is a precision, single-channel SPST analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum on-resistance of 35Ω and operates within an extended temperature range of -40°C to +85°C. The device supports dual supply voltages from ±4.5V to ±20V or a single supply from +9V to +36V. It utilizes +3V logic-compatible digital inputs with thresholds of 0.8V for low and 2.0V for high. The component is housed in an 8-pin SOIC package.

Feature Summary

+3V Logic-Compatible Digital Inputs
Power-Supply Sequencing-Free Operation
Rail-to-Rail Analog Signal Handling Capability

Applications

Sample-and-Hold Circuits
Communications Systems
Test Equipment

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status through current datasheets as specifications may be updated. Ensure compatibility with existing PCB footprints before finalizing procurement decisions.

Selection Notes

Select this component when a single-pole/single-throw configuration is required alongside +3V logic compatibility. Verify that the 35Ω on-resistance meets system signal integrity requirements. Confirm that the 8-pin SOIC package dimensions align with the target board layout constraints.

Part Context

This part belongs to the DG417L/DG418L/DG419L family of precision CMOS analog switches. The DG418L variant specifically provides a normally open single-pole/single-throw (SPST) configuration. It serves as a direct upgrade path for legacy industry-standard DG417/DG418/DG419 devices without requiring power-supply sequencing modifications.
