DG201ADJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201ADJ+ is a quad single-pole single-throw (SPST) normally closed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on dual power supplies ranging from ±4.5V to ±18V and features a 16-pin Plastic DIP package with an operating temperature range of -40°C to +85°C. The device guarantees break-before-make switching, has a maximum turn-on time of 600ns, and a maximum turn-off time of 450ns. It draws a maximum supply current of 0.1mA and supports continuous drain-source currents up to 20mA.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed break-before-make switching prevents signal overlap during transitions.
• Nonlatching design ensures safe operation even if power supplies are disconnected while input signals remain connected.
• CMOS and TTL logic compatible for straightforward interface integration.

• Winchester Disk Drives
• Test Equipment
• Communications Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component matches the specific DG201ADJ+ designation, confirming the -40°C to +85°C industrial temperature grade and 16-pin Plastic DIP packaging. Ensure the supplier provides documentation confirming compliance with RoHS standards as indicated by the '+' suffix in the part number.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low power consumption and nonlatching behavior are required for portable or battery-operated systems. It eliminates the need for a third VL supply voltage compared to legacy designs. Consider the DG211 variant only if slower switching speeds are acceptable.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG201A/DG211 family of quad SPST CMOS analog switches. The DG201A specifically offers faster switching characteristics than the DG211. These devices are designed to replace older discrete solutions, offering monolithic integration and reduced power dissipation suitable for modern electronic applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG211ADJ+ serves as a direct functional substitute within the same family, differing primarily in slower switching specifications. Other generic quad SPST CMOS switches may require circuit redesign due to differences in latch-up protection and power supply requirements.
