Overview
The DG408CUE+T is an improved CMOS analog multiplexer switch manufactured by Analog Devices Inc./Maxim Integrated. It features a single 8:1 circuit configuration housed in a 16-TSSOP surface-mount package. The device operates with a single supply voltage ranging from 5V to 30V or dual supplies of ±5V to ±20V. Key electrical specifications include a maximum on-resistance of 100 Ohms, a channel-to-channel matching of 1.5 Ohms, and a maximum leakage current of 500pA. Switching times are limited to 150ns for both turn-on and turn-off periods, with a charge injection of 2pC. The component supports an operating temperature range of 0°C to +70°C.
Feature Summary
- CMOS technology ensures low power consumption and high input impedance.
- Improved performance characteristics including reduced on-resistance and leakage current compared to standard variants.
- Single 8:1 multiplexing architecture simplifies signal routing in complex systems.
Applications
- Data acquisition systems requiring multi-channel signal selection.
- Industrial process control instrumentation.
- Medical equipment signal conditioning circuits.
Procurement Notes
Verify the specific suffix 'T' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 16-TSSOP footprint matches the design layout exactly. Cross-reference the manufacturer part number DG408CUE+T with authorized distributors to avoid counterfeit parts. Check for any recent lifecycle notices regarding obsolescence or alternative recommendations.
Selection Notes
Select this component when a single 8-channel multiplexer is required within the specified voltage ranges. The 100 Ohm on-resistance suits applications where moderate signal attenuation is acceptable. Consider the TSSOP-16 package constraints for PCB space limitations. Evaluate thermal dissipation requirements against the specified operating temperature range of 0°C to +70°C. Compare leakage current specs if handling high-impedance sensors.
Part Context
This part belongs to the DG408 series of improved CMOS analog switches. It serves as a modern replacement for older discrete switching solutions. The device integrates eight independent channels into a compact form factor. It is designed for general-purpose analog signal routing tasks. The series emphasizes reliability and consistent performance across industrial environments.
Replacement Considerations
The DG408CY+ is a pin-compatible variant available in SOIC-16 packaging. The DG408EUE+ offers extended temperature ratings up to +85°C in TSSOP-16. Verify electrical parameter compatibility before substituting these alternatives. Ensure package dimensions match the existing board layout for direct replacement.
