Overview
The AD7528LR-REEL, produced by Analog Devices Inc., is a monolithic dual 8-bit digital-to-analog converter (DAC) known for its excellent DAC-to-DAC matching. This component is particularly useful in applications requiring precise analog output control, such as audio, graphics, and process control systems. The AD7528 is available in various packages, including skinny 0.3" wide 20-lead DIPs and 20-terminal surface mount packages. Although the AD7528LR-REEL is currently obsolete and no longer manufactured, it remains a significant component in the history of digital-to-analog conversion technology.
