Overview
The DG509AMY/PR is a dual SP4T analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two independent multiplexer circuits, each configured as a single-pole quadruple-throw switch with a maximum on-resistance of 450 ohms. The device operates within a supply voltage range of ±4.5V to ±18V and supports a single supply of 4.5V to 18V. It is housed in a 20-pin PLCC surface-mount package and is rated for an operating temperature range of -20°C to +85°C.
Feature Summary
- Dual-channel architecture providing two independent SP4T switching paths
- CMOS technology enabling low power consumption and high input impedance
- Robust mechanical design suitable for through-hole or surface-mount integration
Applications
- Signal routing in test and measurement equipment
- Data acquisition systems requiring multi-channel selection
- Industrial control panels for sensor signal switching
Procurement Notes
Verify the specific suffix 'AMY/PR' against official manufacturer documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure the component meets current RoHS directives if required by your assembly process. Cross-reference the part number with authorized distributors to confirm availability status and lead times.
Selection Notes
Select this component when dual independent 4-to-1 signal routing is required within a compact form factor. Verify that the 450-ohm on-resistance aligns with your signal integrity requirements. Confirm that the ±18V maximum supply voltage covers your system's operational range and that the PLCC package fits your PCB footprint constraints.
Part Context
This part belongs to the DG509 family of CMOS analog switches, which are designed for general-purpose signal switching applications. The family typically includes variants with different packaging options such as DIP and SOIC. The DG509 series is characterized by its balanced performance between speed and power consumption, making it a standard choice for moderate-speed multiplexing tasks.
Replacement Considerations
Direct replacements include the ADG509AKNZ and ADG509AKR from Analog Devices. Other compatible alternatives may include the MPC509AP from Texas Instruments, though pinout and electrical parameter verification is essential before substitution.
