Overview
The DG333ADW-E3 is a precision quad SPDT analog switch manufactured by Vishay Siliconix, housed in a 20-pin wide-body SOIC package. It features four independently controlled single-pole double-throw switches designed for high-accuracy analog signal control. The device operates with a supply voltage range of 5 V to 40 V (single) or ±4 V to ±22 V (dual). Key electrical parameters include a maximum on-resistance of 45 Ω at room temperature and up to 90 Ω across the full operating temperature range (-40 °C to +85 °C). Maximum turn-on time is 175 ns, while maximum turn-off time is 145 ns. The typical charge injection is 10 pC, and the maximum positive supply current is 200 μA.

- Low on-resistance and low leakage performance
- Low charge injection capability
- Micro-power operation
Applications
- Audio switching
- Test equipment
- Portable instrumentation
- Communication systems
- Switched-capacitor networks
Procurement Notes
Verify the exact ordering suffix against the manufacturer's official documentation to confirm package type and shipping format. The '-E3' designation indicates lead-free finish compliance. Confirm that the specific variant matches the required operational temperature limits and power dissipation ratings for the target application environment before finalizing procurement.
Selection Notes
Select this component when a quad SPDT configuration with precision matching is required. Ensure the design accommodates the specified maximum on-resistance variation across the full temperature range. Verify that the logic input thresholds align with the system's digital control levels. Consider the package thermal characteristics and derating requirements if the application involves significant power dissipation.
Part Context
This part belongs to the DG333A/DG333AL family of precision analog switches from Vishay Siliconix. The 'D' suffix denotes the 20-pin wide-body SOIC package. The 'W' typically indicates the tape and reel shipping option, though standard tubes are also listed for this package style in some distributor data. It is functionally similar to other members of the DG series but distinguished by its specific channel count and package form factor.

FAQ
What is the maximum on-resistance flatness for the DG333ADW-E3?
The maximum on-resistance flatness is 3 Ω at room temperature and 5 Ω across the full operating temperature range, measured under bipolar supply conditions.
How does the DG333ADW-E3 handle signals exceeding the supply rails?
Signals on the source (Sx), drain (Dx), or input (Inx) pins exceeding V+ or V- will be clamped by internal diodes. The forward diode current must be limited to the maximum current ratings specified in the absolute maximum ratings section.
What is the break-before-make time delay for this switch?
The break-before-make time delay is guaranteed to be a minimum of 5 ns at room temperature.
