GENERAL DESCRIPTION
The AD5399 is the industry-first dual 12-bit digital-to-analog converter that accepts twos complement digital coding with 2 V dc offset for single-supply operation. Augmented with a built-in precision reference and a solid buffer amplifier, the AD5399 is the smallest self-contained 12-bit precision DAC that fits many general-purpose as well as DSP specific applications. The twos complement programming facilitates the natural coding implementation commonly found in DSP applications, and allows operation in single supply.
