DG333ADW-T1-E3

Overview

The DG333ADW-T1-E3 is a precision quad single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of 5 V to 40 V for single-supply or ±4 V to ±22 V for dual-supply configurations. The device features a maximum on-resistance of 45 Ω at room temperature and up to 90 Ω across the full operating temperature range of -40 °C to +85 °C. Key electrical specifications include a maximum turn-on time of 175 ns, a maximum turn-off time of 145 ns, and a typical leakage current of 20 pA. The component is housed in a 20-pin wide-body SOIC package and is supplied in tape and reel format.

Feature Summary

• Four independently controlled SPDT analog switches designed for high-accuracy signal routing
• Low charge injection performance to minimize measurement errors
• Micro-power operation with low supply current consumption
• Internal diode clamping on control pins to protect against overvoltage

Applications

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

Procurement Notes

Verify the complete part number including the suffix to confirm the specific package type and shipping method. The '-T1' designation indicates tape and reel packaging, while the '-E3' denotes lead-free termination compliant with RoHS standards. Confirm that the required quantity aligns with the manufacturer's standard reel size to avoid partial reel handling fees or ordering discrepancies.

Selection Notes

Select this component when precise analog signal routing is required with minimal distortion. The DG333A variant offers low on-resistance and leakage suitable for general-purpose applications. Ensure the application voltage does not exceed the absolute maximum ratings of 40 V single supply or ±22 V dual supply. Consider the thermal derating requirements if the power dissipation exceeds the specified limits for the SOIC-20 package.

Part Context

This part belongs to the DG333A/DG333AL family of precision analog switches from Vishay Siliconix. It shares functional characteristics with other members of the series but differs in packaging and shipping configuration. The 'D' suffix identifies the wide-body SOIC package, distinguishing it from DIP or TSSOP variants within the same product line.

Replacement Considerations

DG333ADW-E3: Identical function and pinout, shipped in tubes instead of tape and reel.

FAQ

What is the logic input threshold voltage?

Logic '0' is defined as 0.8 V or lower, and Logic '1' is defined as 2.4 V or higher.

How does the device handle overvoltage on control pins?

Signals on Sx, Dx, or INx exceeding V+ or V- are clamped by internal diodes to prevent damage.

What is the maximum power dissipation for the SOIC-20 package?

The maximum power dissipation is 800 mW, with a derating factor of 12 mW/°C above 75 °C.
