DG419LDY+T

Overview

The DG419LDY+T is a single-channel SPDT analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes LC2MOS technology to achieve low power dissipation and high switching speed. The device operates with a single supply voltage ranging from 10V to 30V or dual supplies of ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 35 Ohms, a break-before-make switching action, and a maximum charge injection of 3pC. It supports a continuous DC current of 30 mA and features an operating temperature range from -40°C to +85°C in an 8-SOIC surface-mount package.

Feature Summary

LC2MOS process technology for low power and fast switching
Break-before-make switching action prevents signal shorting
Ultralow power dissipation characteristics
Logic-compatible input structure

Applications

Precision test equipment
Battery-powered systems
Sample-and-hold circuits

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated for this specific part number. Confirm the suffix indicates tape and reel packaging. Check RoHS compliance status against current regulatory requirements. Ensure the source document matches the DG419LDY+T identifier to avoid confusion with similar variants like the DG419DY+T or non-T versions.

Selection Notes

Select this component when a single SPDT switch with moderate on-resistance is required. It is suitable for applications needing low power consumption and fast switching speeds. Consider the 8-SOIC package for surface-mount designs. Verify that the 35 Ohm on-resistance meets the signal integrity requirements of the specific circuit application.

Part Context

The DG419 belongs to the improved series of SPST/SPDT analog switches. It serves as a plug-in replacement for older discrete switch solutions. The device is part of a family including the DG417 and DG418, offering enhanced performance over previous generations while maintaining compatibility with standard logic families.
