DG411CJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411CJ+ is a monolithic quad single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four independent switches in a 16-pin PDIP package with through-hole mounting. The device supports single supply voltages from 10V to 30V or dual supplies from ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 45 Ohms, a maximum operating speed of 175ns for turn-on and 145ns for turn-off, and a maximum power dissipation of 842mW. It operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and electrical tolerances. Ensure the selected variant matches the required operating temperature range and packaging style for the target design. Cross-reference manufacturer datasheets to validate RoHS compliance status and lead-free specifications before integration into production schedules.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration with low on-resistance is required for bidirectional signal routing. Consider the 16-pin PDIP package for through-hole assembly needs. Evaluate the 45 Ohm on-resistance and 175ns switching speed against system bandwidth requirements. Confirm that the 10V to 30V single supply range aligns with the available power rails in the application environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG411 series serves as an improved replacement for the legacy DG211 and DG212 devices. It offers lower analog on-resistance and faster switching times compared to its predecessors. The series includes variants like the DG412 (normally open) and DG413 (mixed logic), providing flexibility for different control logic requirements while maintaining the same physical footprint and basic functionality.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG411DJ+ is a confirmed surface-mount alternative offering identical electrical characteristics in a 16-DIP package format.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the DG411 and DG412?

The DG411 and DG412 are electrically identical but differ in the polarity of their selection logic. The DG411 is normally closed, while the DG412 is normally open.

Does the DG411 support single or dual supply operation?

Yes, the DG411 supports both single-ended supply operation from +5V to +44V and split supply operation from ±5V to ±20V.

What is the maximum voltage range permitted for signal control?

The device permits controlling signals up to 40V peak-to-peak due to its 44V maximum voltage range capability.
