Overview
The DG407EWI+ is a dual 8-channel CMOS analog multiplexer in a 28-pin Wide SOIC package. It operates with single supplies from +5V to +30V or dual supplies from ±4.5V to ±20V. Key electrical specifications include a maximum on-resistance of 175Ω, an on-resistance matching of 8Ω, and a flatness of 9Ω. The device features a maximum charge injection of 15pC, input leakage current under 5nA at +85°C, and low power consumption of 1.25mW. Transition time is typically 300ns, with enable turn-on/off times up to 600ns and 300ns respectively. It supports rail-to-rail signal handling and includes ESD protection exceeding 2000V.
Feature Summary
- Pin-compatible plug-in upgrade for industry standard DG406/DG407
- Guaranteed low charge injection and low on-resistance
- Digital input controls compatible with TTL and CMOS logic levels
- Rail-to-rail signal handling capability
Applications
- Sample-and-Hold Circuits
- Test Equipment
- Guidance and Control Systems
- Data-Acquisition Systems
Procurement Notes
Verify the specific suffix 'EWI+' corresponds to the 28-pin Wide SOIC package and -40°C to +85°C temperature range. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the ordering code matches the exact manufacturer part number to avoid pinout mismatches with legacy devices.
Selection Notes
Select this component when a dual 8-channel configuration is required instead of a single 16-channel unit. Verify that the 175Ω maximum on-resistance meets system requirements. Check if the Wide SOIC footprint fits the PCB layout constraints compared to DIP or PLCC alternatives.
Part Context
This device belongs to the DG406/DG407 series of improved CMOS analog multiplexers. It serves as a direct replacement for older DG506A/DG507A series devices while offering enhanced performance metrics such as lower on-resistance and faster switching speeds.

FAQ
What is the maximum analog signal voltage range?
The device supports a maximum analog signal range of ±20V with dual supplies or up to 30V with a single supply.
How does the DG407 differ from the DG406?
The DG407 is configured as two independent 8-channel multiplexers, whereas the DG406 is a single 16-channel multiplexer.
