Overview
The DG441EEE is a quad, single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four independent channels with normally closed logic configuration. The device operates on a single supply voltage ranging from 10V to 30V or dual supplies of ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum charge injection of 5pC, and an off-state leakage current of 500pA. Switching times are specified at a maximum of 250ns for turn-on and 120ns for turn-off. The component supports a continuous DC switch current of 30mA and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent SPST analog switches in a single package
- Supports both single and dual power supply configurations
- Features low charge injection characteristics for signal integrity
- Provides high isolation with low off-state leakage current
Applications
- Signal routing in data acquisition systems
- Audio signal switching applications
- Instrumentation control circuits
- Communication equipment signal paths
Procurement Notes
Verify the specific suffix 'EEE' against official Analog Devices documentation to confirm package type and material specifications. Ensure compatibility with required operating temperatures and supply voltages. Cross-reference datasheet revisions for any changes in pinout or electrical limits before integration into final designs.
Selection Notes
Select this component when a quad SPST switch with normally closed logic is required. Consider the 85 Ohm on-resistance limit and 30mA current capability for load matching. Evaluate the 250ns/120ns switching speeds against system timing requirements. Confirm that the available packages align with PCB layout constraints.
Part Context
The DG441 series represents improved quad SPST analog switches designed for general-purpose signal switching. This family offers enhanced performance over previous generations with lower charge injection and faster switching times. The DG441EEE variant specifically denotes a particular package and thermal profile within the broader DG441 product line offered by Analog Devices.
Replacement Considerations
Publicly confirmed substitute part numbers for the DG441EEE are not explicitly listed in the provided source material. Users should consult official Analog Devices documentation for verified cross-reference options.
