DG411LDQ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411LDQ-E3 is a precision monolithic quad single-pole single-throw (SPST) low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies from ±3 V to ±6 V. The device features a maximum drain-source on-resistance of 33 Ω at ±5 V, with turn-on and turn-off times of 50 ns and 35 ns respectively under dual supply conditions. It utilizes TSSOP-16 surface-mount packaging and supports an operating temperature range from -40 °C to +85 °C.

Ensure that the TSSOP-16 package dimensions match the design footprint requirements. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low-voltage operation between 2.7 V and 12 V is required. The DG411L variant provides specific control logic distinct from companion devices like the DG412L. Verify that the 33 Ω on-resistance meets the signal integrity requirements for the intended application bandwidth and current levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG411LDQ-E3 belongs to the DG411L family, which serves as a low-voltage counterpart to the industry-standard DG411 series. These devices utilize BiCMOS wafer fabrication technology to achieve improved performance characteristics while maintaining pin-for-pin compatibility with legacy high-voltage versions in the same product line.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic sense of the DG411L switches?

The DG411L responds to opposite control logic compared to the DG412L. A logic '0' turns the switches ON, while a logic '1' turns them OFF.

Does the DG411L support break-before-make switching?

Yes, the DG411L features break-before-make switching action, which prevents short circuits during signal path transitions.

What is the maximum analog signal range for the DG411L?

The analog signal range extends across the full supply rails, allowing signals to swing from V- to V+ without restriction.
