Overview
The DG509ADY-T is a dual SP4T analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two independent multiplexer circuits, each configured as a 4-to-1 switch. The device utilizes a 16-CDIP package for through-hole mounting. It operates with dual power supplies ranging from ±4.5V to ±18V or a single supply of 4.5V to 36V. Key electrical characteristics include a maximum on-resistance of 450 ohms and a channel-to-channel matching of 27 ohms. Switching times are specified at a maximum of 1.5µs for turn-on and 1µs for turn-off. The component supports an operating temperature range from -20°C to +85°C.
Feature Summary
- Dual independent SP4T switching architecture providing four channels per circuit
- Low leakage current specification suitable for precision signal routing
- Compatible with standard digital logic control interfaces
- Robust mechanical packaging designed for through-hole PCB integration
Applications
- Signal routing in test and measurement equipment
- Data acquisition systems requiring multi-channel selection
- Industrial process control signal conditioning
- Communication system front-end switching
Procurement Notes
Verify the specific suffix 'DY-T' against official manufacturer documentation to confirm tape-and-reel availability and exact pinout configuration. Cross-reference the part number with Analog Devices or Maxim Integrated databases to ensure compliance with current RoHS directives and material declarations. Confirm that the 16-CDIP package dimensions match the target footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when dual 4-to-1 switching functionality is required within a single package. Ensure the application voltage does not exceed the ±18V dual supply limit. Verify that the 450-ohm on-resistance meets the signal integrity requirements of the connected circuitry. Consider the through-hole mounting style if surface area constraints allow for larger footprints compared to SOIC alternatives.
Part Context
This part belongs to the DG509 family of analog switches, which are designed for general-purpose signal switching applications. The family typically includes variants with different resistance levels and package options. The DG509 series is characterized by its low power consumption and high isolation between switched channels, making it suitable for maintaining signal fidelity in complex electronic systems.
Replacement Considerations
Direct replacements may include other dual SP4T analog switches from the same manufacturer family. Check for equivalent packages such as CDIP-16 or PLCC-20 variants. Verify that substitute parts offer comparable on-resistance and switching speed specifications to maintain circuit performance without redesign.
