DG411FDY+

Overview

The DG411FDY+ is a quad, single-pole/single-throw (SPST) CMOS analog switch featuring fault protection and rail-to-rail signal handling. It operates with dual supplies from ±4.5V to ±20V or a single supply between +9V and +36V. The device provides on-resistance of 35Ω maximum at +25°C, matched between channels to 1.5Ω maximum. Fault protection allows terminals to withstand up to ±36V with power on and ±40V with power off. Digital inputs are TTL and CMOS compatible. The component is housed in a 16-pin SOIC package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

Rail-to-Rail signal handling capability across the full supply voltage range
Fault protection for all switch terminals against overvoltage conditions
TTL and CMOS logic input compatibility without power-supply sequencing requirements
Pin-compatible replacement for industry-standard non-protected switches

Applications

Communication Systems
Signal Routing
Test Equipment
Data Acquisition
Industrial and Process Control Systems

Procurement Notes

Verify the specific ordering suffix 'DY+' corresponds to the 16-pin Small Outline package type when sourcing components. Confirm that the manufacturer designation matches Analog Devices Inc./Maxim Integrated specifications. Ensure compliance with environmental standards such as RoHS requirements associated with the plus sign suffix before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high-voltage fault tolerance on analog signal paths. The DG411FDY+ is suitable where rail-to-rail operation is necessary within ±4.5V to ±20V dual or +9V to +36V single supply configurations. Consider the 35Ω on-resistance and 175ns turn-on time for bandwidth and switching speed requirements.

Part Context

The DG411F series belongs to a family of monolithic CMOS analog switches designed as drop-in replacements for older DG211/DG212 devices. The FDY variant specifically denotes the surface-mount SOIC package option within the broader DG411F/DG412F/DG413F product line, offering identical electrical characteristics to through-hole counterparts.

FAQ

How does the DG411FDY+ handle overvoltage faults?

During a fault condition, the affected terminal becomes a high-impedance open circuit. Leakage current remains in the microampere range even when voltages exceed supply rails by up to ±36V with power on.

What is the logic compatibility of the digital inputs?

The digital inputs feature +0.8V and +2.4V logic thresholds, ensuring compatibility with both TTL and CMOS logic levels when using ±15V or a single +12V supply.
