DG411DJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411DJ+ is a quad single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a temperature range of -40°C to +85°C and utilizes a 16-pin Plastic DIP package. The device supports single-supply voltages from +10V to +30V or bipolar supplies from ±4.5V to ±20V. Key electrical specifications include a maximum on-resistance of 45Ω, an on-resistance match between channels of 3Ω max, and on-resistance flatness of 4Ω max. Switching times are characterized by a maximum turn-on time of 175ns and a maximum turn-off time of 145ns. The component features low charge injection of 10pC max and low power consumption.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status through current datasheets. Ensure the supply voltage and logic levels align with system requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed analog switching configuration is required. Verify that the bipolar or single-supply voltage ranges meet the application's signal handling needs. Consider the 16-pin PDIP package constraints for PCB layout and thermal dissipation requirements during the design phase.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411/DG412/DG413 series of improved quad SPST analog switches. The DG411 variant specifically provides a normally closed switch configuration, distinguishing it from the normally open DG412 and the mixed DG413. These devices serve as drop-in replacements for older industry-standard CMOS switches while offering enhanced performance metrics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411DJ+ serves as a direct replacement for legacy DG411 devices in existing designs. Verify pin compatibility and logic polarity when substituting with DG412 or DG413 variants, as these differ in switch state behavior.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic configuration of the DG411?

The DG411 features a normally closed (NC) logic configuration, meaning the switches conduct when the input is low and disconnect when the input is high.

How does the DG411 handle electrostatic discharge?

The device guarantees a minimum electrostatic discharge tolerance of 2000V per Method 3015.7.

What is the maximum on-resistance flatness specified for this component?

The on-resistance flatness (ΔRDS(ON)) is guaranteed to be a maximum of 4Ω over the specified analog signal range.
