+AD4052-ARDZ HDL project
+================================================================================
+
+Overview
+--------------------------------------------------------------------------------
+
+The HDL reference design for the :adi:`AD4050`, :adi:`AD4052`, :adi:`AD4056`, and
+:adi:`AD4058` .
+They are versatile, 16-bit/12-bit, successive approximation register (SAR)
+analog-to-digital converters (ADCs) that enable low-power, high-density data
+acquisition solutions without sacrificing precision. These ADCs offer a unique
+balance of performance and power efficiency, plus innovative features for
+seamlessly switching between high-resolution and low-power modes tailored to the
+immediate needs of the system.
+
+The :adi:`AD4050`/:adi:`AD4052`/:adi:`AD4056`/:adi:`AD4058` are ideal for
+battery-powered, compact data acquisition and edge sensing applications.
+
+The :adi:`EVAL-AD4050-ARDZ`/:adi:`EVAL-AD4052-ARDZ` evaluation boards enable
+quick and easy evaluation of the performance and features of the :adi:`AD4050`
+or the :adi:`AD4052`, respectively.
+The AD4050 and AD4052 are compact, low power, 12-bit or 16-bit (respectively)
+Easy Drive successive approximation register (SAR) analog-to-digital converters
+(ADCs).
+
+This project has a :ref:`spi_engine` instance to control and acquire data from
+the precision ADC.
+This instance provides support for capturing continuous samples at the maximum
+sample rate.

+
+Building the HDL project
+-------------------------------------------------------------------------------
+
+The design is built upon ADI's generic HDL reference design framework.
+ADI distributes the bit/elf files of these projects as part of the
+:dokuwiki:`ADI Kuiper Linux `.
+If you want to build the sources, ADI makes them available on the
+:git-hdl:`HDL repository `. To get the source you must
+`clone `__
+the HDL repository, and then build the project as follows:
+
+**Linux/Cygwin/WSL**
+
+.. shell::
+
+ $cd hdl/projects/ad4052_ardz/coraz7s
+ $make
+
+.. shell::
+
+ $cd hdl/projects/ad4052_ardz/de10nano
+ $make
+
+A more comprehensive build guide can be found in the :ref:`build_hdl` user guide.
