Overview
The DG409DJ is a dual 4-channel CMOS analog multiplexer/demultiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with single supplies from +5V to +30V or dual supplies from ±5V to ±20V. The device features a maximum on-resistance of 175Ω, guaranteed channel matching of 8Ω max, and flatness of 9Ω max. Key electrical parameters include a maximum charge injection of 15pC, input leakage current under 5nA at +85°C, and low power consumption of 1.25mW max. It provides ESD protection exceeding 2000V per MIL-STD-883 Method 3015.7 and supports rail-to-rail signal handling within the supply range.
Feature Summary
- Pin-compatible plug-in upgrade for industry standard DG408/DG409
- Guaranteed low charge injection and low input off-leakage current over temperature
- Digital input controls compatible with TTL/CMOS logic levels
- High ESD protection rating exceeding 2000V
Applications
- Sample-and-Hold Circuits
- Test Equipment
- Guidance and Control Systems
- Communications Systems
- Data-Acquisition Systems
- Audio Signal Routing
Procurement Notes
Verify the specific suffix 'DJ' corresponds to the Plastic DIP package and -40°C to +85°C temperature range as listed in official documentation. Confirm RoHS compliance status through manufacturer declarations. Ensure ordering details match the exact pin count and package dimensions required for the target PCB layout.
Selection Notes
Select this component when a dual 4-channel configuration is required instead of an 8-channel single unit. Consider the 175Ω maximum on-resistance for signal integrity requirements. Verify that the digital control inputs align with the system's voltage levels. Check if the Plastic DIP package suits the assembly process compared to surface-mount alternatives.
Part Context
This part belongs to the DG408/DG409 series of improved CMOS analog multiplexers. It serves as a direct replacement for legacy versions while offering enhanced performance metrics such as lower charge injection and better channel matching. The series is designed for applications requiring reliable signal switching in data acquisition and control environments.
