DGQ4052EEQ-T1-GE4

Overview

The DGQ4052EEQ-T1-GE4 is a high precision CMOS analog multiplexer manufactured by Vishay Siliconix. It integrates two independent 4-channel single-pole double-throw (SPDT) switches within a single 16-pin TSSOP package. The device supports operation from a 3 V to 16 V single supply or ± 3 V to ± 8 V dual supplies, ensuring compatibility with various logic levels including 3 V systems. Key electrical characteristics include low charge injection of less than 0.3 pC and typical on-resistance values ranging from 68 Ω to 176 Ω depending on the supply voltage. The component is qualified to AEC-Q100 Grade 1 standards and operates reliably across an extended temperature range of -40 °C to +125 °C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 reliability standards
• Dual 4-channel SPDT configuration enabling independent signal routing
• Ultra-low charge injection below 0.3 pC for high-fidelity signal integrity
• Bi-directional rail-to-rail switching capability across wide voltage ranges

Applications

• Automotive battery management systems
• Automotive infotainment and telematics signal processing
• Multiplexing and demultiplexing of analog and digital signals in vehicles

Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to confirm the exact temperature range and packaging configuration. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Cross-reference the manufacturer part number with current datasheet revisions to validate compliance with RoHS3 specifications before finalizing orders.

Selection Notes

Select this component when designing automotive circuits requiring dual independent 4-channel switching with strict signal fidelity constraints. The low charge injection specification makes it suitable for precision measurement applications where signal distortion must be minimized. Verify that the system power supply falls within the specified 3 V to 16 V single or ± 3 V to ± 8 V dual ranges to ensure proper logic threshold compatibility and optimal on-resistance performance.

Part Context

This part belongs to the DGQ405xE family of low capacitance analog multiplexers designed specifically for automotive environments. It shares functional similarities with the DGQ4051E and DGQ4053E but offers a distinct dual 4-channel topology rather than an 8-channel or triple 2-channel arrangement. All variants in this series utilize the same 16-pin TSSOP footprint and share common control logic interfaces.

FAQ

What is the maximum analog signal voltage range supported by the DGQ4052EEQ-T1-GE4?

The device supports rail-to-rail analog signal switching, allowing the analog voltage to span the full range between the negative and positive supply rails.

How does the DGQ4052EEQ-T1-GE4 handle bi-directional signal flow?

All switches conduct equally well in both directions, allowing the device to function effectively as both a multiplexer and a de-multiplexer without performance degradation.

What are the guaranteed logic high input limits for the control pins?

The device guarantees a 2 V logic high limit when operating from 5 V or ± 5 V supplies, and a 1.4 V limit when operating from a 3 V supply.
