DG444DJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG444DJ is a quad, single-pole/single-throw (SPST) analog switch featuring four normally closed channels in a 16-pin Plastic DIP package. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Key electrical parameters 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. The device supports turn-on times up to 250ns and turn-off times up to 120ns. It offers low charge injection of 10pC max, off-leakage current less than 5nA at +85°C, and ESD tolerance of 2000V min per Method 3015.7. Operating temperature range is -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 16-pin Plastic DIP configuration. Confirm that the component meets required environmental standards such as RoHS compliance if applicable to the design specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when normally closed analog switching is required within the specified voltage ranges. Consider the 85Ω maximum on-resistance and 250ns switching speed for bandwidth and latency requirements. Verify that the bipolar or single-supply operation aligns with the system's power architecture and logic level compatibility needs.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG444DJ belongs to the DG444/DG445 family of improved quad SPST analog switches manufactured by Analog Devices Inc./Maxim Integrated. This series represents a redesign offering better performance metrics compared to legacy versions, specifically regarding on-resistance matching and leakage currents.
