DG407CWI

Analog Switches, Multiplexers, Demultiplexers Overview

The DG407CWI+ is a dual 8-channel CMOS analog multiplexer housed in a 28-pin Wide SOIC package. 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. Charge injection is limited to 15pC, while input off-leakage current remains below 5nA at +85°C. Transition time reaches 300ns, and the unit supports rail-to-rail signal handling with TTL/CMOS compatible digital inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation against official manufacturer documentation to confirm the specific suffix indicates the Wide SOIC package and commercial temperature range. Ensure that ordering requirements align with lead-free and RoHS compliance standards as defined by the supplier. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement actions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 8-channel configuration is required for bidirectional analog signal routing. The wide supply voltage range accommodates both single and split power rails. Verify that the 100Ω on-resistance and 300ns transition times meet system bandwidth and latency specifications. Confirm that the 28-pin Wide SOIC footprint fits the target PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG406/DG407 series of improved CMOS analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. The series replaces older industry-standard devices with enhanced performance metrics including lower on-resistance and reduced charge injection. The DG407 specifically provides two independent 8-channel multiplexing functions within a single integrated circuit package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the DG407CJ+, DG407DJ+, DG407EWI+, DG407DN+, and DG407EUI+. These variants offer identical functionality but differ in package type or operating temperature range.
