DG444DY

Overview

The DG444DY is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features an on-resistance of 85 ohms maximum and operates within a supply voltage range of +10V to +30V or bipolar ±4.5V to ±20V. The device provides switching times of 250ns maximum for turn-on and 120ns maximum for turn-off. It is housed in a 16-pin Narrow SOIC package with an operating temperature range from -40°C to +85°C.

Feature Summary

Improved on-resistance matching between channels
Guaranteed low charge injection performance
Low power consumption characteristics
High electrostatic discharge tolerance

Applications

Sample-and-hold circuits
Test equipment signal routing
Audio signal routing systems

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status through current datasheets as specifications may evolve. Ensure logic level compatibility matches system requirements before integration.

Selection Notes

Select this component when high channel-to-channel resistance matching is required for precision applications. Verify that the narrow SOIC package fits the available PCB footprint. Check that the bipolar supply range meets the analog signal handling needs of the circuit design.

Part Context

This part belongs to the DG444/DG445 family of improved analog switches. It serves as a redesign offering better performance metrics compared to industry-standard predecessors while maintaining pin compatibility. The series focuses on reducing charge injection and improving leakage current stability over temperature variations.

Replacement Considerations

DG444CY+ offers identical electrical specifications but operates within a commercial temperature range of 0°C to +70°C instead of the industrial range.
