DG411DK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411DK is a monolithic CMOS analog switch featuring four independent single-pole/single-throw (SPST) channels in a 16-pin CERDIP 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 45Ω, an on-resistance match between channels of 3Ω max, and on-resistance flatness of 4Ω max over the signal range. Switching times are specified with a maximum turn-on time of 175ns and a maximum turn-off time of 145ns. The device guarantees low charge injection of 10pC max and off-leakage current less than 5nA at +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features improved on-resistance matching between channels and guaranteed on-resistance flatness over the signal range for high-fidelity signal routing.
• Provides enhanced electrostatic discharge tolerance of 2000V minimum per Method 3015.7 for robust operation in sensitive environments.
• Offers reduced charge injection and lower off-leakage current across temperature ranges to simplify sample-and-hold applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix DK against official manufacturer documentation to confirm the ceramic dual in-line package configuration and -40°C to +85°C operating temperature range. Ensure compatibility with system voltage requirements and logic levels before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed SPST analog switch is required with tight on-resistance matching specifications. Verify that the 16-pin CERDIP package meets the mechanical constraints of the target design and that the bipolar or single supply voltages align with the available power rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG411DK belongs to the DG411/DG412/DG413 series of improved quad SPST analog switches. Unlike the standard DG411 which is typically offered in plastic DIP or SO packages, the DK suffix specifically denotes the ruggedized ceramic dual in-line package variant designed for extended industrial temperature ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG411DJ serves as a direct functional substitute within the same series but utilizes a plastic DIP package instead of ceramic. Both share identical electrical characteristics and pinouts, allowing for drop-in replacement if the packaging material difference is acceptable.
