ADSP-1081AKD

Overview

The ADSP-1081AKD is an 8-bit DSP multiplier peripheral manufactured by Analog Devices Inc. It is housed in a hermetically sealed, side-brazed ceramic DIP-28 package with 28 pins. The component features an 8-bit external data bus width and a 16-bit output data bus width. It operates within a military-grade temperature range from -55 °C to +125 °C. The device is classified as a DSP Peripheral under the Embedded Processors and Controllers category.

Feature Summary

• Hermetically sealed ceramic construction for environmental protection
• Side-brazed DIP-28 package configuration
• Integrated 8-bit DSP multiplier functionality

Applications

• Military aerospace systems requiring hermetic sealing
• High-reliability embedded signal processing applications
• Harsh environment digital signal control circuits

Procurement Notes

Verify the specific suffix AKD against official Analog Devices documentation to confirm the exact package variant and temperature grade. Ensure compatibility with existing hermetic packaging requirements. Confirm that the 8-bit data bus interface aligns with the target system architecture. Check for end-of-life status or obsolescence notices prior to procurement planning.

Selection Notes

Select this component when hermetic sealing and high-temperature operation are mandatory. The 8-bit multiplier core suits specific legacy DSP architectures. Compare pin counts and bus widths against alternative ceramic DIP packages. Validate that the 16-bit output width meets the downstream processing requirements of the design.

Part Context

This part belongs to the ADSP-1000 series of DSP peripherals from Analog Devices. It shares functional similarities with other hermetic ceramic DSP multipliers like the ADSP-1080AKD, though pin counts and package sizes differ. These components are designed for specialized industrial and military applications where standard plastic packages are insufficient.

Replacement Considerations

Direct replacements include the ADSP-1080AKD, which offers similar hermetic ceramic construction but differs in pin count and package dimensions. Verify mechanical fit and electrical interface compatibility before substitution.
