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.
Feature Summary
- Enhanced LC2MOS process technology ensures ultralow power dissipation while maintaining fast switching speeds.
- Break-before-make switching action prevents signal overlap during state transitions.
- Wide supply voltage capability allows compatibility with various single and dual power systems.
- Low charge injection and leakage characteristics support precision signal routing applications.
Applications
- Precision test equipment requiring accurate signal path control
- Battery-powered instrumentation systems prioritizing low power consumption
- Sample-and-hold circuits demanding minimal charge injection errors
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.
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.
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.
Replacement Considerations
The DG419CJ+ serves as a commercial grade alternative within the same package type. For military specifications, the DG417AK/883B offers comparable functionality with extended reliability standards. Verify pinout compatibility before substituting.
