DG411FDJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411FDJ+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features fault protection for inputs up to ±36V with power on and ±40V with power off. The device operates from dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. On-resistance is typically 35Ω at ±15V supplies. Switching times are 175ns turn-on and 145ns turn-off. It uses a 16-pin Plastic DIP package and operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'FDJ+' corresponds to the 16-pin Plastic DIP package and the -40°C to +85°C operating temperature range as documented in the official datasheet. Confirm that the component is sourced from authorized distributors to ensure authenticity and compliance with RoHS standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required for analog signals exceeding standard supply rails. Ensure the application supports the specified voltage ranges and switching speeds. Consider the PDIP-16 package constraints for PCB layout and thermal management during design integration.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411F/DG412F/DG413F family of quad SPST analog switches. The DG411F variant specifically provides four normally closed (NC) switches. It serves as an enhanced version of the standard DG411, adding robust fault protection while maintaining pin compatibility with legacy designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacement with standard DG411 devices is possible but will lack the integrated fault protection features. Verify that any substitute maintains the same 16-pin PDIP footprint and electrical characteristics to ensure circuit functionality without modification.
