DG413FEUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG413FEUE+ is a quad, single-pole/single-throw (SPST) CMOS analog switch featuring fault protection and rail-to-rail signal handling. It integrates two normally open and two normally closed switches within a 16-pin TSSOP package. The device operates on dual supplies from ±4.5V to ±20V or a single supply between +9V and +36V. Key electrical parameters include a maximum on-resistance of 35Ω at +25°C with ±15V supplies, an on-resistance match of 1.5Ω, and a typical charge injection of 5pC. Fault protection tolerates signals up to ±36V during power-on and ±40V when powered off.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation matches the exact part number provided in official manufacturer documentation. Confirm that the ordering suffix corresponds to the specified 16-pin TSSOP package type. Ensure compliance with relevant environmental standards as indicated in the product specifications before integration into designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when mixed SPST configurations are required alongside robust fault protection. The device supports both single and split power supply architectures. Verify that the operating voltage range aligns with the system's available power rails and that the thermal dissipation capabilities meet the application's requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG41xF series of quad SPST analog switches manufactured by Analog Devices / Maxim Integrated. It serves as a pin-compatible upgrade to standard non-protected switches, offering enhanced reliability through integrated fault protection circuitry while maintaining identical physical dimensions and pin assignments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG413FEUE+ is a direct pin-compatible replacement for the industry-standard DG413. Designers can substitute it into existing layouts without modifying the printed circuit board footprint, as the NO, NC, and COM pins retain their original positions.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the DG413FEUE+ handle overvoltage faults?

During a fault condition where the signal exceeds the supply rails, the affected terminal becomes a high-impedance open circuit. This protects the internal FETs and limits leakage current to microamperes.

What is the break-before-make time delay for this device?

For the DG413F variant, the break-before-make time delay is typically 15ns and guaranteed not to exceed 50ns under specified test conditions.

Can the DG413FEUE+ operate with asymmetric power supplies?

Yes, the V+ and V- supplies do not need to be symmetrical. However, the total difference between them must not exceed the absolute maximum rating of 44V.
