Overview
The DG406CWI+ is a CMOS analog multiplexer featuring a 1-of-16 channel configuration housed in a 28-pin Wide SO package. It operates with single supplies from +5V to +30V or dual supplies from ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 175Ω under single supply conditions and 125Ω under dual supply conditions, with a maximum on-resistance matching of 8Ω. The device guarantees low charge injection of 15pC (max) and input off-leakage current below 5nA at +85°C. Digital inputs are TTL/CMOS compatible, and the component supports an operating temperature range of 0°C to +70°C.
Feature Summary
- Pin-compatible plug-in upgrade for industry standard DG406/DG407
- Guaranteed low charge injection and low input leakage current over temperature
- Rail-to-rail signal handling capability
- ESD protection exceeding 2000V per MIL-STD-883 Method 3015.7
Applications
- Sample-and-Hold Circuits
- Test Equipment
- Guidance and Control Systems
- Communications Systems
- Data-Acquisition Systems
Procurement Notes
Verify the specific suffix 'CWI+' against official documentation to confirm the Wide SO package type and the 0°C to +70°C industrial temperature rating. Ensure that the lead-free/RoHS-compliant status indicated by the '+' symbol aligns with project requirements. Cross-reference the manufacturer's ordering information to validate availability and confirm that no additional functional changes are associated with the selected package variant.
Selection Notes
Select this component when a high-channel-count multiplexer with guaranteed channel matching is required. The wide supply voltage range accommodates various system architectures. Verify that the 175Ω on-resistance meets the application's signal integrity needs. Confirm that the digital control logic levels match the system's TTL/CMOS interface standards before finalizing the design integration.
Part Context
This part belongs to the DG406/DG407 series of improved CMOS analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. The series is designed as a direct replacement for legacy industry-standard parts, offering enhanced performance metrics such as lower charge injection and better on-resistance flatness while maintaining pin compatibility.
Replacement Considerations
The DG406CWI+ serves as a pin-compatible upgrade for the standard DG406. Verify that any substitute maintains the 28-pin Wide SO footprint and matches the critical electrical specifications, particularly the on-resistance and leakage current limits, to ensure seamless integration without circuit redesign.
