DG413LDJ-E3

Overview

The Vishay Siliconix DG413LDJ-E3 is a dual SPST analog switch featuring low on-resistance and fast switching speeds. It operates with a single supply voltage ranging from +4.5V to +26V or dual supplies of ±4.5V to ±13V. The device utilizes CMOS technology for low power consumption and high input impedance. Key electrical parameters include an on-resistance (Ron) of typically 10 ohms, channel-to-channel matching of 0.1 ohm, and a breakdown voltage of 26V. It supports continuous current flow of 25mA per channel and offers low charge injection and crosstalk, making it suitable for precision signal routing applications.

Feature Summary

• Dual single-pole single-throw (SPST) configuration for independent channel control
• Low on-resistance ensures minimal signal attenuation in the pass state
• CMOS construction provides high input impedance and low power dissipation
• Fast switching characteristics support high-frequency signal processing

Applications

• Data acquisition systems requiring precise analog signal routing
• Audio signal switching and matrix routing
• Instrumentation and test equipment signal paths
• Communication systems for line termination and selection

Procurement Notes

Verify the specific suffix E3 indicates lead-free compliance according to RoHS standards. Confirm the package type matches the required board layout, as the DJ suffix denotes a plastic DIP package. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the manufacturer's latest datasheet for any updates on recommended soldering profiles and storage conditions to maintain component integrity during assembly.

Selection Notes

Select this component when dual independent analog switches are required with low on-resistance and moderate speed. Consider the supply voltage constraints, as operation requires voltages within the specified positive or dual-rail ranges. Evaluate the maximum continuous current rating against the load requirements to prevent overheating. Verify that the package dimensions fit the available PCB space and that the thermal performance meets the system's heat dissipation capabilities under expected duty cycles.

Part Context

This part belongs to the DG41x series of analog switches, which are designed for general-purpose signal switching. The DG413 variant specifically offers two independent channels. Compared to higher-speed variants, this model balances performance with cost-effectiveness for standard data acquisition tasks. The series is known for its compatibility with standard logic levels and robust protection features against electrostatic discharge.

Replacement Considerations

Direct substitutes may include other dual SPST CMOS analog switches with similar Ron and voltage ratings. Verify pinout compatibility before substitution to avoid circuit redesign. Check if alternative parts offer improved switching speeds or lower on-resistance if performance upgrades are needed. Ensure the replacement maintains the same package style for mechanical fit.
