DG412LDQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412LDQ-T1-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 on-resistance of 33 Ω at ±5 V, with turn-on and turn-off times reaching 50 ns and 35 ns respectively under standard test conditions. It utilizes a 16-pin Thin Shrink Small Outline Package (TSSOP), supports an operating temperature range of -40 °C to +85 °C, and includes 2000 V ESD protection.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as the local source indicates it may be obsolete. Confirm RoHS compliance through the specific suffix designation. Ensure the TSSOP-16 package matches the design footprint. Validate that the supply voltage requirements align with the 2.7 V to 12 V single or ±3 V to ±6 V dual supply specifications provided in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low voltage operation and fast switching are required. The DG412L offers opposite control logic compared to the DG411L. Verify the on-resistance flatness over the analog signal range if linearity is critical. Consider the power dissipation limits of the TSSOP package relative to the thermal environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411L/DG412L/DG413L family of low-voltage analog switches. These devices are pin-for-pin compatible companions to the industry-standard DG411/412/413 series but feature improved performance using BiCMOS wafer fabrication technology. They are designed for applications requiring wide dynamic range and low signal distortion.
