ADSP-1081ASD/883B

Overview

The ADSP-1081ASD/883B is an 8x8 CMOS digital multiplier manufactured by Analog Devices Inc. It performs high-speed multiplication operations in digital signal processing applications. The component is housed in a hermetically sealed CDIP40 ceramic package with side brazed construction, measuring 0.600 inches (15.24mm). It functions as an 8-bit DSP multiplier optimized for precision arithmetic tasks.

Feature Summary

• Hermetically sealed CDIP40 ceramic package with side brazed construction
• High-speed 8x8 CMOS digital multiplication capability
• Optimized for digital signal processing applications

Applications

• Digital signal processing systems
• Precision arithmetic operations
• Military and aerospace electronics requiring hermetic sealing

Procurement Notes

Verify the specific suffix /883B indicates military-grade hermetic packaging when sourcing. Confirm pin compatibility with existing designs. Check current availability status as this may be a limited supply item. Ensure the supplier provides valid traceability documentation for the ceramic package integrity.

Selection Notes

Select this component when hermetic sealing is required for 8x8 multiplication. Compare against standard plastic packages if environmental protection is not critical. Verify that the CDIP40 footprint matches the target PCB layout. Consider thermal dissipation requirements associated with the ceramic housing.

Part Context

This part belongs to the ADSP series of digital signal processors from Analog Devices. It is designed for specialized arithmetic functions rather than general-purpose computing. The /883B suffix typically denotes compliance with MIL-STD-883 standards for microelectronics devices.

Replacement Considerations

Check for pin-compatible alternatives within the ADSP family. Verify if non-hermetic versions like ADSP-1081ASD meet environmental requirements. Consult Analog Devices for current recommended replacements if this part is discontinued.
