Overview
The DG508AEWE is a monolithic CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features an 8:1 configuration with eight input channels and one common output, housed in a 16-SOIC surface-mount package. The device operates on dual power supplies ranging from ±4.5 V to ±18 V. Key electrical specifications include a maximum on-resistance of 450 Ohms, a channel-to-channel matching of 27 Ohms, and a maximum leakage current of 1 nA. Switching performance is defined by a maximum turn-on time of 1.5 µs and a turn-off time of 1 µs. The component supports an operating temperature range of -40°C to +85°C.
Feature Summary
- Monolithic CMOS construction for high reliability and low power consumption
- Single 8:1 multiplexing circuit topology
- Low leakage current characteristics suitable for precision signal routing
Applications
- Data acquisition systems requiring multi-channel signal selection
- Process control instrumentation
- Industrial automation signal conditioning
Procurement Notes
Verify the specific suffix 'EWE' against official manufacturer documentation to confirm pinout compatibility and package dimensions. Ensure that the dual supply voltage requirements align with the target system design before integration. Cross-reference the RoHS status and environmental compliance data provided in the latest datasheet to meet regulatory standards for the intended deployment region.
Selection Notes
Select this component when an 8-channel analog switch is required within a narrow SOIC footprint. The 450 Ohm on-resistance limit defines its suitability for lower-impedance signal paths. Compare the 1.5 µs switching speed against application timing constraints. Verify that the ±4.5 V minimum supply voltage meets the system's power budget and signal swing requirements.
Part Context
This part belongs to the DG508A series of analog multiplexers. It shares functional similarities with other devices in the family but differs in packaging and specific electrical tolerances. The 'EWE' designation indicates a specific tape-and-reel or tube variant within the SOIC-16 form factor, distinct from through-hole DIP versions like the DG508ADJ+.
Replacement Considerations
Direct substitutes may include other 8:1 CMOS multiplexers with similar on-resistance and package constraints. Verify pin compatibility and electrical parameters such as leakage current and switching speed before substitution.
