Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the component matches the specific ordering code DG411DY+. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the package type corresponds to the 16-pin Narrow SO configuration. Validate the extended industrial temperature rating of -40°C to +85°C against project requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low on-resistance matching and guaranteed flatness across the signal range. It is suitable for systems needing rail-to-rail signal handling with TTL/CMOS-compatible logic inputs. Consider the power dissipation limits when designing thermal management solutions for the narrow SO package.

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 utilizes normally closed switches. These devices are fabricated using a 44V silicon-gate process designed to prevent latch-up and ensure high reliability in precision analog switching applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411DY+ serves as a plug-in upgrade for industry-standard DG411 devices. Verify pin compatibility and electrical parameter improvements such as reduced charge injection and better on-resistance matching when substituting older generations of the same family.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic sense of the DG411?

The DG411 consists of four normally closed (NC) switches. A logic '0' input turns the switch ON, while a logic '1' input turns it OFF.

How does the DG411 handle overvoltage protection?

Signals on S, D, or IN exceeding V+ or V- are clamped by internal diodes. For proper sequencing, V+ should be powered on first, followed by VL, V-, and logic inputs.

What is the maximum analog signal range?

The device supports a bipolar supply operation from ±4.5V to ±20V and a single supply operation from +10V to +30V, allowing for rail-to-rail signal handling within these limits.
