AD9002TD/883B

Overview

The AD9002TD/883B is a high-speed 8-bit flash analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features parallel access output and operates within an extended military temperature range of -55°C to +125°C. The device utilizes a ceramic dual in-line package (CDIP-28) with side brazed construction, designed for rugged environments. Key electrical specifications include a maximum linear error of 0.4688% and binary output format. The component requires negative supply voltages, with a nominal value of -5.2 V, and supports a maximum analog input voltage of 0.1 V.

Feature Summary

• 8-bit resolution with flash conversion method
• Parallel digital output interface
• Military-grade temperature range (-55°C to +125°C)
• Ceramic DIP-28 package with side brazed seal

Applications

• High-speed data acquisition systems requiring radiation hardness
• Military radar signal processing
• Aerospace instrumentation and control
• Harsh environment test equipment

Procurement Notes

Verify the authenticity of the AD9002TD/883B through authorized distributors or direct manufacturer channels due to its specialized military specification nature. Confirm that the part number suffix /883B indicates compliance with MIL-PRF-38534 standards. Ensure proper handling procedures are followed for ceramic packages to maintain hermetic seal integrity during installation.

Selection Notes

Select this component when an 8-bit resolution at high speeds is required in extreme thermal conditions. The CDIP-28 package necessitates specific PCB footprint designs compatible with side-brazed ceramic DIPs. Verify power supply requirements, particularly the -5.2 V nominal rail, against system capabilities. Consider the parallel interface complexity compared to serial alternatives if pin count is constrained.

Part Context

This part belongs to the AD9002 family of flash ADCs from Analog Devices. The /883B suffix denotes a version qualified under military reliability standards, distinguishing it from commercial variants. It serves as a critical component in applications demanding high reliability and performance stability beyond standard industrial limits.

Replacement Considerations

Direct replacements must match the 8-bit flash architecture, CDIP-28 package, and military temperature rating. Cross-reference with other ADI military-qualified ADCs such as the AD9002 series variants. Ensure pin compatibility and electrical parameter alignment before substitution.
