DG407EWI

Overview

The DG407EWI+ is a dual 8-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 ±4.5V to ±20V. The device features a maximum on-resistance of 100Ω, guaranteed channel matching of 8Ω, and flatness of 9Ω. Input off-leakage current is less than 5nA at +85°C. It provides ESD protection exceeding 2000V per MIL-STD-883 Method 3015.7. The component is housed in a 28-pin Wide SO package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

Pin-compatible plug-in upgrade for industry standard DG406/DG407
Guaranteed low charge injection of 15pC maximum
Digital input controls compatible with TTL/CMOS logic levels
Rail-to-rail signal handling capability

Applications

Sample-and-Hold Circuits
Test Equipment
Guidance and Control Systems
Communications Systems
Data-Acquisition Systems

Procurement Notes

Verify the specific suffix 'EWI+' corresponds to the 28-pin Wide SO package and the -40°C to +85°C industrial temperature grade. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the ordering information matches the manufacturer's current datasheet revision to avoid discrepancies in pinout or electrical specifications.

Selection Notes

Select this component when a dual 8-channel configuration is required instead of a single 16-channel unit. Verify that the supply voltage range meets the application needs, noting that switching times may increase significantly at lower voltages like 5V. Ensure the load conditions do not exceed the continuous current ratings specified in the absolute maximums.

Part Context

This part belongs to the DG406/DG407 series of improved CMOS analog multiplexers. It serves as a direct replacement for legacy versions while offering enhanced performance metrics such as lower on-resistance and better channel matching. The series is designed for applications requiring high reliability and bidirectional signal routing.
