ADSP-1080AJN

Overview

The ADSP-1080AJN is a high-performance 8-bit digital signal processor (DSP) multiplier manufactured by Analog Devices. It features a ceramic dual in-line package (CDIP) with 40 pins, designed for robust industrial and military applications. The device operates within a temperature range of -55°C to +125°C, ensuring reliability in extreme environments. It supports an external data bus width of 8 bits and provides a 16-bit output data bus width for precise signal processing tasks.

Feature Summary

• High-speed 8-bit DSP multiplier architecture optimized for real-time signal processing
• Hermetically sealed ceramic construction for enhanced environmental durability
• Wide operating temperature range suitable for harsh industrial conditions

Applications

• Military radar systems requiring hermetic sealing
• Industrial process control automation
• Aerospace avionics signal processing

Procurement Notes

Verify the specific suffix code against the manufacturer's datasheet to confirm pinout compatibility and performance grade. Ensure the procurement channel provides traceability documentation for hermetically sealed ceramic packages. Confirm that the component meets the required MIL-STD specifications if used in defense applications. Check for any recent product change notifications regarding material composition or manufacturing location changes.

Selection Notes

Select this component when a hermetically sealed 8-bit DSP multiplier is required for high-reliability environments. Compare power dissipation characteristics against thermal management capabilities in the final enclosure. Evaluate the 40-pin CDIP footprint against available PCB space and mounting constraints. Consider the 8-bit external bus interface requirements for system integration complexity.

Part Context

The ADSP-1080AJN belongs to the ADSP-1080 family of 8-bit DSP multipliers from Analog Devices. This series is known for its precision analog multiplication capabilities integrated with digital control logic. The AJN suffix typically denotes a military-grade temperature range and hermetic packaging, distinguishing it from commercial variants like the ADSP-1080AJD.

Replacement Considerations

Direct replacements include the ADSP-1080AJD for non-hermetic applications or the ADSP-1080AKD for ceramic DIP versions. Verify pin compatibility and thermal resistance values before substitution. Cross-reference with JM38510/13901BIA equivalents if military sourcing is required.
