Overview
The DG308ACY is a quad single-pole single-throw (SPST) normally-open analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four independent channels with a maximum on-resistance of 100 ohms. The device operates on a single supply voltage ranging from 5V to 30V or dual supplies of ±5V to ±20V. Key electrical specifications include a maximum charge injection of -10pC, off-channel capacitance values of 11pF and 8pF, and a maximum leakage current of 5nA. Switching times are specified at 200ns for turn-on and 150ns for turn-off. The component is designed for surface-mount installation in a die package configuration.
Feature Summary
- Provides four independent SPST signal paths for analog switching applications
- Operates within wide single and dual power supply voltage ranges
- Features low charge injection characteristics for signal integrity
Applications
- Signal routing in data acquisition systems
- Multiplexing in measurement instrumentation
- Audio and video signal switching circuits
Procurement Notes
Verify the specific suffix 'ACY' against official manufacturer documentation, as standard listings often reference 'DG308AC/D'. Confirm end-of-life status and obsolescence notices directly with Analog Devices or Maxim Integrated, as distribution availability may be limited. Ensure compatibility with existing board layouts regarding the die package format.
Selection Notes
Select this component when a quad SPST configuration with moderate on-resistance is required. Verify that the 100-ohm on-resistance meets system loss requirements. Check if the die package type is suitable for the intended assembly process, as it differs from standard leaded or QFN packages. Compare charge injection specs against other switches if high-fidelity signal handling is critical.
Part Context
The DG308 belongs to the broader family of CMOS analog switches produced by Maxim Integrated, now part of Analog Devices. This series typically offers high isolation and low power consumption. The DG308 specifically integrates four independent switches, providing a compact solution for multi-channel signal management compared to using individual single-switch ICs.
Replacement Considerations
Publicly confirmed substitute part numbers for the DG308ACY are not available in the provided source material. Consult manufacturer cross-reference guides for potential alternatives such as the DG309 or DG310 series, ensuring pinout and electrical parameter compatibility.
