DG413DY+

Overview

The DG413DY+ is a monolithic quad single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It integrates two normally closed and two normally open switches within a 16-pin Narrow SO package, operating from +10V to +30V single supplies or ±4.5V to ±20V bipolar supplies. The device features a maximum on-resistance of 45Ω, an on-resistance match between channels of 3Ω max, and guaranteed flatness of 4Ω over the signal range. Switching times are limited to 175ns for turn-on and 145ns for turn-off, with charge injection capped at 5pC.

Feature Summary

• Integrates four independent SPST switches with mixed logic polarity for flexible break-before-make or make-before-break configurations.
• Features low on-resistance matching and guaranteed flatness across the analog signal range for high-fidelity signal routing.
• Provides enhanced electrostatic discharge tolerance and reduced off-leakage current over temperature variations.

Applications

• Sample-and-Hold Circuits
• Communication Systems
• Test Equipment

Procurement Notes

Verify that the ordering suffix 'DY+' corresponds to the specific 16-pin Narrow SOIC package variant required for your design. Confirm that the component meets RoHS compliance standards as indicated by the plus sign in the part number. Ensure the selected supplier provides traceability documentation consistent with Analog Devices specifications.

Selection Notes

Select this component when mixed logic control is necessary to manage break-before-make timing without external logic gates. Verify that the supply voltage range aligns with the system's power architecture. Consider the 45Ω on-resistance limit for applications requiring lower signal attenuation compared to standard CMOS switches.

Part Context

This device belongs to the redesigned DG411/DG412/DG413 series, serving as a drop-in replacement for legacy industry-standard parts. It utilizes a 44V silicon-gate process to prevent latch-up while maintaining compatibility with TTL and CMOS logic levels. The DG413 specifically combines NC and NO functions to simplify circuit topology.

Replacement Considerations

Direct replacements include DG411DY+ and DG412DY+. Verify logic polarity requirements before substitution, as DG411 is entirely NC and DG412 is entirely NO.

FAQ

How does the DG413 handle logic inputs?

Switches 1 and 4 use positive logic, while switches 2 and 3 use negative logic, allowing independent control of turn-on and turn-off states.

What is the maximum analog signal range?

The switches can handle rail-to-rail signals within the limits of the applied power supply voltages, up to a maximum differential of 44V.
