Overview
The AD664SD-BIP/883B is a quad 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features an R-2R architecture with buffered voltage outputs and parallel data interfaces. The device operates within a temperature range of -40°C to +85°C and is housed in a 28-pin ceramic dual in-line package (CDIP). Supply voltages include ±11.4V to 16.5V for analog circuits and 5V for digital logic. Key performance metrics include a maximum settling time of 10µs, integral nonlinearity (INL) of ±0.5 LSB, and differential nonlinearity (DNL) of ±0.5 LSB.
Feature Summary
- Quad 12-bit resolution with R-2R architecture
- Buffered voltage outputs for high drive capability
- Parallel interface supporting standard digital logic levels
- Military-grade qualification indicated by /883B suffix
Applications
- High-performance military radar systems
- Aerospace signal processing equipment
- Precision test and measurement instrumentation
Procurement Notes
Verify the authenticity of the /883B suffix, which denotes compliance with MIL-PRF-38534 or similar military standards. Confirm that the ceramic package integrity meets aerospace requirements. Check for recent Product Change Notices regarding wafer fabrication site updates. Ensure supply chain sources provide traceability documentation for qualified components.
Selection Notes
Select this component when four independent 12-bit channels are required in a single package. The buffered output design eliminates the need for external op-amps, reducing board space. Verify that the parallel interface timing aligns with the system controller. Consider the thermal dissipation characteristics of the CDIP package for enclosure design.
Part Context
This part belongs to the AD664 family of high-speed DACs. The SD variant specifies the specific pinout and electrical characteristics distinct from other members like the AD664BD. The /883B designation indicates screening to military reliability standards, differentiating it from commercial grade parts.
Replacement Considerations
The AD664BD-BIP is a functional equivalent within the same family. Verify pin compatibility and electrical parameter alignment before substitution. Ensure the replacement part meets the same environmental and reliability qualifications if used in critical applications.
