Overview
The DG507AEWI+ is a dual 8-to-1 analog multiplexer switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two independent 8:1 switching circuits within a single package, providing flexible signal routing capabilities. The device operates with a supply voltage range of 4.5V to 20V for dual supplies or 9V to 36V for single supplies. Key electrical specifications include a maximum on-resistance of 175 Ohms and a channel-to-channel matching of 10 Ohms. Switching times are characterized by a maximum turn-on time of 600 ns and a maximum turn-off time of 300 ns. The component supports an operating temperature range from -40°C to +85°C and is housed in a 28-pin SOIC wide package.
Feature Summary
- Dual independent 8:1 multiplexer configuration for efficient signal path management
- Low on-resistance with tight channel-to-channel matching for signal integrity
- Fast switching speeds suitable for high-frequency data acquisition systems
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial process control instrumentation
- Medical equipment signal routing
Procurement Notes
Verify the specific suffix AEWI against official Analog Devices documentation to confirm the industrial temperature grade and SOIC package variant. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements before procurement.
Selection Notes
Select this component when dual isolated 8-channel switching is required within a compact surface-mount footprint. Compare on-resistance and leakage current specifications against alternative parts if precise signal attenuation limits are critical for the application design.
Part Context
This part belongs to the DG407/DG507 family of CMOS analog multiplexers. It serves as a dual-channel variant designed to replace older relay-based switching solutions in modern electronic systems, offering improved reliability and smaller form factors.
Replacement Considerations
Direct replacements may include other DG507 variants with different temperature grades or packages, such as DG507EWI+. Verify pin compatibility and electrical parameter tolerances before substitution.
