DG441LDQ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441LDQ-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It integrates four independent channels in a 16-pin TSSOP surface-mount package. The device supports dual supply voltages ranging from ±3V to ±6V and single supplies from 2.7V to 12V. Key electrical specifications include a maximum on-resistance of 30 Ohms, a bandwidth of 280MHz, and charge injection of 5pC. Switching times are specified at a maximum of 60ns for turn-on and 35ns for turn-off. The component operates within a temperature range of -40°C to +85°C and draws a maximum supply current of 1µA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

This component is officially classified as obsolete or not recommended for new designs. Verification of availability should focus on surplus distributors rather than direct manufacturer allocation. Buyers must confirm the specific revision status and ensure that any existing stock meets current RoHS compliance standards before procurement planning.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Designers should evaluate the 30 Ohm on-resistance and 280MHz bandwidth against signal requirements. The TSSOP-16 package limits thermal dissipation compared to through-hole alternatives. Consider the ±3V to ±6V dual supply range when designing power rails. Verify if the obsolete status impacts long-term maintenance strategies for the target application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG441LDQ-E3 belongs to the DG441L series of CMOS analog switches. It serves as the surface-mount variant of the DIP-based DG441LDJ-E3. The 'E3' suffix indicates lead-free construction compliant with RoHS directives. This part is distinct from the higher-voltage DG441DY-E3, which utilizes an SOIC-16 package and supports wider voltage ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly documented substitutes include the ADG1611BRUZ from Analog Devices. Designers should verify pin compatibility and electrical parameter alignment when considering alternative components due to the obsolete status of the original part.
