Overview
The AD7528JP-REEL, produced by Analog Devices Inc., is a monolithic dual 8-bit digital/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. It features separate on-chip latches for each DAC, facilitating easy interface with microprocessors. The device operates within a power supply range of +5V to +15V and dissipates only 20mW of power, making it energy-efficient.
