DG333ADW

Analog Switches, Multiplexers, Demultiplexers Overview

The DG333ADW is a precision quad single-pole double-throw (SPDT) analog switch in a 20-pin wide-body SOIC package. It features low on-resistance of 25 Ω typical and leakage current of 20 pA typical. The device operates with supply voltages ranging from ±4 V to ±22 V for dual supplies or up to 40 V for single supplies. Key electrical parameters include a maximum turn-on time of 175 ns, off-isolation of 72 dB, and charge injection of 10 pC. The DG333A variant draws less than 1 μA of supply current.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the exact ordering suffix matches the required package and tape/reel configuration. The DG333ADW-E3 denotes the standard wide-body SOIC shipped in tubes. Ensure the logic voltage levels align with system requirements, noting that the DG333AL variant includes a dedicated VL pin for micro-power operation while the DG333A does not. Confirm temperature range specifications for the intended operating environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG333ADW when a 20-pin wide-body SOIC package is required for quad SPDT switching. Choose the DG333AL variant if micro-power consumption is critical, as it offers significantly lower supply current compared to the standard DG333A. Verify that the analog signal range fits within the specified supply voltage limits. Consider the break-before-make timing characteristics for applications requiring glitch-free switching.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG333ADW belongs to the Vishay Siliconix DG333A/DG333AL family of precision analog switches. This series is engineered for applications demanding low distortion and high accuracy. The 'D' suffix indicates the wide-body SOIC package, while 'W' specifies the tube shipping method for the -E3 version. The component is part of a broader portfolio of monolithic analog switches designed for industrial and consumer electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same package include the DG333ADJ-E3 (plastic DIP) and DG333ADQ-T1-E3 (TSSOP). Cross-family replacements may require verification of pin compatibility and electrical parameter alignment. No other specific cross-manufacturer part numbers are confirmed in the provided documentation.
