Overview
The DG407EWI+T is a dual 8-to-1 analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates within a single supply voltage range of 5 V to 30 V or dual supplies up to ±20 V. The device features a maximum on-resistance of 175 Ohms, with a typical turn-on time of 600 ns and turn-off time of 300 ns. Propagation delay is specified at 300 ns. It supports power dissipation of 1 W and draws a maximum supply current of 500 uA. The component is housed in a 28-SOIC (Wide) package and functions across an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual independent 8:1 multiplexing architecture for signal routing
- CMOS technology enabling low power consumption and high input impedance
- Wide single and dual supply voltage compatibility for flexible system integration
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. Confirm RoHS compliance status through official manufacturer documentation. Ensure the SOIC-Wide-28 footprint matches the target PCB layout. Cross-reference the full part number against current distributor listings to confirm availability and authenticity.
Selection Notes
Select this component for applications requiring dual 8-channel switching with moderate speed requirements. Compare on-resistance specifications against other series members if lower resistance is needed. Verify thermal performance under maximum power dissipation conditions. Ensure supply voltage ranges align with the system's available power rails.
Part Context
This part belongs to the DG407 family of improved CMOS analog multiplexers. It shares functional similarities with the DG407EWI+ but differs in packaging format. The family provides reliable analog signal switching for precision applications. Other variants include DIP packages and military-grade options.
Replacement Considerations
The DG407EWI+ serves as a direct pin-compatible alternative with tube packaging. Verify that the change from reel to tube does not impact automated assembly processes. Check for any minor parameter variations between the two packaging styles.
