ADSP-1081AKD/+

Overview

The ADSP-1081AKD/+ is an 8-bit DSP multiplier integrated circuit manufactured by Analog Devices Inc. It features a ceramic dual in-line package with 28 pins, designed for hermetic sealing and side brazing. The device operates within a temperature range of -55 °C to 125 °C. It utilizes an 8-bit external data bus width and provides a 16-bit output data bus width. The component is classified as a DSP peripheral and is housed in a CDIP28 package.

Feature Summary

• Hermetically sealed ceramic construction with side brazing for environmental protection
• Designed for high-temperature operation up to 125 °C
• Integrated 8-bit DSP multiplier functionality

Applications

• Military aerospace systems requiring radiation-hardened or hermetic components
• Industrial control environments with extreme temperature variations
• Defense communication equipment

Procurement Notes

Verify the specific suffix designation (+) against official Analog Devices documentation to confirm hermetic sealing requirements and pinout compatibility. Ensure that the lead finish and material composition meet project specifications, as this component may not comply with standard RoHS directives due to its specialized packaging and intended use cases.

Selection Notes

Select this component when hermetic sealing and wide operating temperature ranges are mandatory. Compare pin counts and bus widths with system requirements. Consider availability from authorized distributors specializing in legacy or military-grade semiconductors. Validate mechanical dimensions against PCB layout constraints before finalizing the design.

Part Context

This part belongs to the ADSP-108x series of digital signal processors. These devices are engineered for high-reliability applications where standard commercial-grade components cannot withstand harsh environmental conditions. The family typically includes variants with different package options and temperature ratings to suit diverse industrial and defense needs.

Replacement Considerations

Consult Analog Devices technical support for verified cross-reference part numbers. Ensure any substitute maintains identical pin configuration, hermetic sealing standards, and electrical characteristics to guarantee system compatibility.
