Overview
The AD667SE/883B is a military-grade, 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. under the MIL-PRF-38534 specification. It integrates a high-stability embedded Zener reference voltage source and dual-buffered input latches on a single chip. The device features a parallel interface, voltage output, and operates within an extended temperature range of -55°C to +125°C. Key electrical parameters include a settling time of 3 µs to 0.01%, differential nonlinearity (DNL) of ±0.5 LSB, and integral nonlinearity (INL) of ±0.25 LSB. It consumes 1 W of power dissipation and utilizes a 28-pin ceramic dual in-line package (CDIP).
Feature Summary
- Military-grade qualification compliant with MIL-PRF-38534 for enhanced reliability.
- Integrated high-stability buried Zener reference voltage source eliminating external components.
- Dual-buffered input latch structure prevents false analog outputs during data updates.
- Guaranteed monotonicity across the full operating temperature range.
Applications
- Aerospace guidance and control systems requiring high reliability.
- Military instrumentation and test equipment.
- Harsh environment industrial control applications.
Procurement Notes
Verify that the component is sourced from an authorized distributor or certified supplier to ensure authenticity. Confirm the presence of the '883B' suffix indicating compliance with MIL-PRF-38534 Batch L screening. Check for physical markings consistent with military lot traceability requirements before integration into critical systems.
Selection Notes
Select this part when military environmental ratings (-55°C to +125°C) and radiation hardness are required. Ensure the design supports the 28-pin CDIP footprint and through-hole mounting. Verify that the system logic levels are compatible with TTL or 5V CMOS inputs as specified for the AD667 family.
Part Context
The AD667SE/883B belongs to the AD667 family of complete 12-bit DACs. While commercial variants like the AD667AD offer similar performance in standard packages, the SE/883B variant provides the rigorous testing and documentation required for defense and aerospace contracts. It replaces older discrete DAC solutions with a monolithic integrated approach.
Replacement Considerations
Direct replacements must match the MIL-PRF-38534 qualification and 28-lead CDIP package. Commercial equivalents such as the AD667AD lack the military screening and may not meet the -55°C to +125°C operational specifications required for this application.
