Overview
The AD7399BRZ, produced by Analog Devices Inc., is a quad, 10-bit, voltage output digital-to-analog converter (DAC). This monolithic DAC is built using the robust CBCMOS process, offering low cost and ease of use in both single and dual-supply systems. It operates from a single 3 V to 5 V supply or a dual ±5 V supply, making it versatile for various applications. The AD7399 is available in 16-lead, wide body SOIC and ultracompact, thin TSSOP packages, ensuring flexibility in design and layout.
