Overview
The DG417DY+T is a monolithic CMOS single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes an enhanced LC2MOS process to deliver low power dissipation, high switching speed, and low on-resistance. The device operates with a single supply voltage ranging from 10 V to 30 V or dual supplies of ±4.5 V to ±20 V. Key electrical parameters include a maximum on-resistance of 35 ohms, a maximum turn-on time of 175 ns, and a maximum turn-off time of 185 ns. It features ultralow power dissipation of less than 35 mW and supports break-before-make switching action. The component is housed in an 8-pin SOIC surface-mount package.
Feature Summary
- Enhanced LC2MOS process technology ensures low power dissipation while maintaining high switching speeds and low leakage currents.
- Break-before-make switching action prevents signal overlap during state transitions, ensuring clean signal routing.
- Wide supply voltage range compatibility allows operation with both single and dual power sources for flexible system integration.
Applications
- Precision test equipment requiring accurate signal switching
- Battery-powered systems benefiting from ultralow power consumption
- Sample-and-hold circuits in data acquisition systems
Procurement Notes
Verify the specific suffix DY+T confirms the SOIC-8 surface-mount package and tape-and-reel shipping format. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the ordering part number matches the required lead-free specifications and packaging quantity defined in the current datasheet revision.
Selection Notes
Select this component when a single-channel SPST configuration is required with moderate on-resistance and standard switching speeds. Verify that the 35-ohm on-resistance meets the signal integrity requirements of the application. Ensure the operating temperature range and supply voltage limits align with the system design constraints before finalizing the selection.
Part Context
The DG417 belongs to the DG417-DG419 family of precision CMOS analog switches. This series is designed as a plug-in replacement for older discrete transistor switches and legacy ICs like the DG417. The family shares similar LC2MOS process characteristics, offering improved performance over previous generations in terms of power efficiency and switching reliability.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult the official Analog Devices cross-reference tools or contact technical support directly to identify verified equivalent components for redesign purposes.
