DG444DY+

Overview

The DG444DY+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed switches in a 16-pin Narrow SOIC package with an operating temperature range of -40°C to +85°C. The device supports single-supply operation from +10V to +30V or bipolar supplies from ±4.5V to ±20V. Key electrical specifications include a maximum on-resistance of 85Ω, an on-resistance match between channels of 4Ω max, and guaranteed on-resistance flatness of 9Ω max over the signal range. Switching times are less than 250ns for turn-on and less than 70ns for turn-off. The component offers low charge injection of 10pC max, low power consumption of 35µW max, and ESD tolerance of 2000V min per Method 3015.7.

Feature Summary

Improved on-resistance matching between channels and guaranteed on-resistance flatness over the signal range.
Low charge injection and low off-leakage current performance across temperature ranges.
High electrostatic discharge tolerance capability.

Applications

Sample-and-hold circuits
Test equipment
Heads-up displays
Guidance and control systems
Military radios

Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. The 'DY' suffix indicates a 16-pin Narrow SOIC package suitable for surface mount applications with an extended industrial temperature range. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.

Selection Notes

Select this component when designing circuits requiring quad SPST switching with improved resistance matching. Verify that the required supply voltage falls within the specified single or bipolar ranges. Consider the package constraints and ensure adequate heat dissipation if operating near maximum power dissipation limits.

Part Context

This part belongs to the DG444/DG445 series of improved analog switches. The DG444 variant specifically provides four normally closed switches, whereas the DG445 provides four normally open switches. Both share similar electrical characteristics and fabrication processes.
