Overview
The DG508AEWE+T is a monolithic CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features an 8-channel (1-of-8) configuration housed in a 16-SOIC surface-mount package. The device operates on dual power supplies ranging from ±4.5V to ±18V, with a typical operating voltage of 15V. Key electrical parameters include a maximum on-resistance of 450 Ohms and a channel-to-channel matching of 27 Ohms. Switching performance is defined by a maximum turn-on time of 1.5µs and a turn-off time of 1µs. The component supports a wide operating temperature range from -40°C to +85°C.
Feature Summary
- Monolithic CMOS construction ensures reliable analog signal switching within specified voltage ranges.
- Guaranteed break-before-make switching action prevents signal overlap during channel transitions.
- Latch-up protection is maintained even if power supplies are removed while input signals remain active.
Applications
- Data acquisition systems requiring multi-channel signal routing
- Industrial process control instrumentation
- Medical equipment signal conditioning
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this part number. Confirm that the manufacturer designation remains Analog Devices Inc./Maxim Integrated for authenticity. Ensure the order matches the exact alphanumeric code to avoid confusion with non-tape variants like the tube-packaged DG508AEWE+. Cross-reference the RoHS status and environmental compliance documentation provided by the supplier.
Selection Notes
Select this component for applications requiring an 8:1 analog multiplexer with moderate on-resistance. The SOIC-16 package suits surface-mount assembly processes. Verify that the required supply voltage falls within the ±4.5V to ±18V operational window. Consider the 450 Ohm on-resistance limit for signal integrity requirements in the target circuit design.
Part Context
This device belongs to the DG508A series of monolithic CMOS analog multiplexers. It serves as a single 8-channel switch variant, distinct from the differential 4-channel DG509A model. The series is characterized by its robust latch-up protection and compatibility with standard digital logic control interfaces for address selection.
Replacement Considerations
Publicly confirmed direct substitutes include the MPC508AU from Texas Instruments. Verify pinout compatibility and electrical parameter alignment before substituting other family members or generic equivalents.
