DG333ALDQ-T1-E3

Overview

The DG333ALDQ-T1-E3 is a precision quad single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It integrates four independently controlled switches in a 20-pin TSSOP package, designed for high-accuracy analog signal routing. The device operates on dual supplies ranging from ±4 V to ±22 V or a single supply up to 36 V. Key electrical characteristics include a typical channel on-resistance of 25 Ω with a maximum of 90 Ω across the full temperature range, and low off-leakage current capped at 20 nA. The DG333AL variant features micro-power operation with supply currents under 1 μA, making it suitable for battery-powered applications.

Feature Summary

Four independent SPDT channels provide precise control over analog signal paths.
Low charge injection minimizes measurement errors during switching events.
Micro-power architecture ensures minimal energy consumption for portable systems.

Applications

Audio switching
Test equipment
Portable instrumentation
Communication systems
Switched-capacitor networks

Procurement Notes

Verify the complete part number against official documentation to ensure correct suffix alignment. Confirm that the DQ-T1 designation matches the required 20-pin TSSOP surface-mount package and tape-and-reel shipping format. Cross-reference the E3 suffix to confirm lead-free compliance status before finalizing procurement specifications.

Selection Notes

Select this component when high accuracy and low leakage are critical requirements. The DG333AL variant is specifically optimized for ultra-low power consumption compared to the standard DG333A. Ensure the application voltage does not exceed the absolute maximum ratings of ±22 V for dual supplies or 36 V for single supplies to maintain device reliability.

Part Context

This component belongs to the DG333 family of precision analog switches. The 'D' indicates the SOIC/TSSOP plastic package type, while 'Q' specifies the TSSOP form factor. The 'T1' suffix denotes tape-and-reel packaging, and 'E3' signifies lead-free termination compliant with RoHS standards.
