Overview
The DG441AK/883B is a quad SPST analog switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for high-reliability applications. It features a CDIP-16 package and supports single or dual power supplies ranging from 10V to 30V (single) or ±4.5V to ±20V (dual). Key electrical parameters include a maximum on-state resistance of 85 Ohms, a maximum channel-to-channel matching of 4 Ohms, and a maximum charge injection of 5pC. The device operates within a temperature range of -40°C to +85°C, with a maximum power dissipation of 696 mW.
Feature Summary
- Quad single-pole single-throw (SPST) configuration for independent signal routing
- Low charge injection characteristics suitable for precision data acquisition
- TTL and CMOS logic compatibility for simplified interface design
Applications
- Precision automatic test equipment
- Data acquisition systems
- Communication systems
Procurement Notes
Verify the authenticity of the DG441AK/883B through authorized channels due to its specialized military-grade designation. Confirm that the component matches the specific MIL-STD-883 qualification requirements intended for your application. Ensure proper handling procedures are followed during installation to maintain the integrity of the ceramic dual in-line package.
Selection Notes
Select this component when a quad SPST switch with low distortion and high reliability is required. Compare the 85 Ohm on-resistance against system tolerance limits. Consider the CDIP-16 package constraints for PCB layout. Verify that the operating voltage range aligns with the available supply rails in the target circuit design.
Part Context
This part belongs to the DG441 series of improved quad SPST analog switches. The AK/883B suffix indicates a specific variant qualified for military standards, distinguishing it from commercial versions like the DG441CY+. It shares functional similarities with other members of the family but offers enhanced performance metrics for demanding environments.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Evaluate generic quad SPST analog switches only if they meet the exact pinout, voltage, and resistance specifications.
