Overview
The AD669BRZ-REEL, produced by Analog Devices Inc., is a high-performance, 16-bit monolithic digital-to-analog converter (DAC) known as the DACPORT. This device integrates a complete 16-bit D/A conversion function, an on-board reference, and an output amplifier on a single chip, utilizing Analog Devices' BiMOS II process. This technology allows for the combination of low power CMOS logic and high precision bipolar linear circuitry on the same chip. The AD669BRZ-REEL is designed for applications requiring high accuracy and stability, with features such as a buried Zener reference and double-buffered latches to eliminate data skew errors.
