Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe AD5399 is the industry-first dual 12-bit digital-to-analog converter that accepts twos complement digital coding ith 2 V dc offset for single-supply operation. Augmented with a built-in precision reference and a solid buffer mplifier, the AD5399 is the smallest self-contained 12-bit precision DAC that fits many general-purpose as well as SP specific applications. The twos complement programming facilitates the natural coding implementation commonly ound in DSP applications, and allows operation in single supply. The AD5399 provides a 2 V reference output, VREF, or bipolar zero monitoring. It can also be used for other on-board components that require a precision reference. The device is specified for operation from 5 V ± 10% single supply with bipolar output swing from 0 V to 4 V centered at 2 V.
The AD5399 is available in the compact 1.1 mm low profile MSOP-10 package. All parts are guaranteed to operate over the extended industrial temperature range of 40°C to +105°C.
