DG419LDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG419LDJ+ is a monolithic CMOS SPDT analog switch manufactured by Analog Devices Inc./Maxim Integrated. It utilizes an enhanced LC2MOS process to deliver low power dissipation, high switching speed, and low leakage currents. The device operates with a single supply voltage ranging from 9V to 36V or dual supplies of ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 35 ohms, a charge injection of 15pC, and a maximum off-leakage current of 250pA. Switching times are specified at a maximum of 175ns for turn-on and 185ns for turn-off. The component is housed in an 8-PDIP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact performance grades and packaging variations. Confirm RoHS compliance status and lead time requirements directly with authorized distributors prior to ordering. Ensure the procurement channel provides valid traceability for quality assurance purposes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT configuration with low on-resistance is required. Verify that the system voltage falls within the 9V to 36V single supply or ±4.5V to ±20V dual supply limits. Consider the 175ns switching speed and 15pC charge injection specifications against application timing and accuracy constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG419 belongs to the DG417/DG419 family of precision mini-DIP analog switches. This series is designed as a plug-in replacement for older discrete transistor switches, offering improved performance in terms of speed and power efficiency while maintaining standard DIP pinouts for easy integration into existing designs.
