Overview
The DG333ALDW-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 wide-body SOIC package. The device supports single supply voltages from 5 V to 40 V and dual supplies ranging from ±4 V to ±22 V. Key electrical parameters include a maximum on-resistance of 45 Ω, a maximum turn-on time of 175 ns, and a maximum turn-off time of 145 ns. It operates within a temperature range of -40 °C to +85 °C.
Feature Summary
- Features micro-power operation with typical supply current below 1 μA for battery-powered applications
- Provides low charge injection performance to minimize measurement errors
- Offers high off-isolation and low crosstalk characteristics
Applications
- Audio switching systems
- Test equipment signal routing
- Portable instrumentation
- Switched-capacitor networks
- Battery-powered systems
Procurement Notes
Verify the complete part number including the suffix to confirm the specific package type and shipping configuration. The '-E3' designation indicates lead-free termination compliant with RoHS standards. Confirm that the wide-body SOIC package matches the intended PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when low power consumption is critical alongside precision analog switching capabilities. Ensure the application voltage does not exceed the absolute maximum ratings of 40 V for single supply or ±22 V for dual supply configurations. Verify that the thermal dissipation limits are respected within the operating temperature range.
Part Context
This part belongs to the DG333A/DG333AL family of precision analog switches. The 'L' suffix specifically denotes the low-power variant optimized for minimal quiescent current draw. It shares functional similarities with other members of the series but differs in power specifications and packaging options such as DIP or TSSOP.
