Overview
The DG411DY+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum on-resistance of 45 Ohms and operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. The device provides a maximum turn-on time of 175ns and a maximum turn-off time of 145ns. It is housed in a 16-pin Narrow SO package and supports an operating temperature range of -40°C to +85°C.
Feature Summary
- Improved on-resistance matching between channels with a maximum variation of 3 Ohms.
- Guaranteed on-resistance flatness over the signal range with a maximum deviation of 4 Ohms.
- Low charge injection capability with a maximum value of 10pC.
- Enhanced off-leakage current performance, remaining below 5nA at +85°C.
Applications
- Sample-and-Hold Circuits
- Communication Systems
- Test Equipment
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.
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.
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.
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.
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.
