Overview
The AD1866RZ-REEL, produced by Analog Devices Inc., is a complete dual 16-bit Digital-to-Analog Converter (DAC) that offers exceptional performance with a single +5V power supply. Fabricated using Analog Devices' ABCMOS wafer fabrication process, this monolithic chip integrates CMOS logic elements, bipolar and MOS linear elements, and laser-trimmed thin-film resistor elements. This design ensures low distortion, low noise, high channel separation, and low power dissipation. The AD1866 is particularly suited for applications requiring high-quality audio output.
