+description: |
+  The AD3530/AD3530R (8-channel) and AD3531/AD3531R (4-channel) are low-power,
+  16-bit, buffered voltage output digital-to-analog converters (DACs) with
+  software-programmable gain controls, providing full-scale output spans of 2.5V
+  or 5V for reference voltages of 2.5V. These devices operate from a single 2.7V
+  to 5.5V supply and are guaranteed monotonic by design. The "R" variants
+  include a 2.5V, 5ppm/°C internal reference, which is disabled by default.
+  Datasheet can be found here:

+  Analog Devices Generic AXI DAC IP core for interfacing a DAC device
+  with a high speed serial (JESD204B/C) or source synchronous parallel
+  interface (LVDS/CMOS).
+  Usually, some other interface type (i.e SPI) is used as a control
+  interface for the actual DAC, while this IP core will interface
+  to the data-lines of the DAC and handle the streaming of data from
+  memory via DMA into the DAC.
