ADAQ7980-SDZ HDL project

===============================================================================
|

|
||||
Overview
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
The :adi:`ADAQ7980`/:adi:`ADAQ7988` are 16-bit analog-to-digital converter
|
||||
(ADC) subsystems that integrate four common signal processing and conditioning
|
||||
blocks into a system in package (SiP) design that supports a variety of
|
||||
applications. These devices contain the most critical passive components,
|
||||
eliminating many of the design challenges associated with traditional signal
|
||||
chains that use successive approximation register (SAR) ADCs. These passive
|
||||
components are crucial to achieving the specified device performance.
|
||||
|
||||
The :adi:`ADAQ7980`/:adi:`ADAQ7988` contain a high accuracy, low power,
|
||||
16-bit SAR ADC, a low power, high bandwidth, high input impedance ADC driver,
|
||||
a low power, stable reference buffer, and an efficient power management block.
|
||||
Housed within a tiny, 5 mm × 4 mm LGA package, these systems simplify the
|
||||
design process for data acquisition systems. The level of system integration
|
||||
of the :adi:`ADAQ7980`/:adi:`ADAQ7988` solves many design challenges, while
|
||||
the devices still provide the flexibility of a configurable ADC driver feedback
|
||||
loop to allow gain and/or common-mode adjustments. A set of four device
|
||||
supplies provides optimal system performance; however, single-supply operation
|
||||
is possible with minimal impact on device operating specifications.
|
||||
|
||||
Using the SDI input, the SPI-compatible serial interface features the ability
|
||||
to daisy-chain multiple devices on a single, 3-wire bus and provides an optional
|
||||
busy indicator. The user interface is compatible with 1.8 V, 2.5 V, 3 V, or 5 V
|
||||
logic. Specified operation of these devices is from −55°C to +125°C.
|
||||

||||

Building the HDL project
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
The design is built upon ADI's generic HDL reference design framework.
|
||||
ADI does not distribute the bit/elf files of these projects so they
|
||||
must be built from the sources available :git-hdl:`here </>`. To get the source
|
||||
you must `clone <https://git-scm.com/book/en/v2/Git-Basics-Getting-a-Git-Repository>`__
|
||||
the HDL repository, and then build the project as follows:.
|
||||
|
||||
**Linux/Cygwin/WSL**
|
||||
|
||||
.. code-block::
|
||||
:linenos:
|
||||
|
||||
user@analog:~$ cd hdl/projects/adaq7980_sdz/zed
|
||||
user@analog:~/hdl/projects/adaq7980_sdz/zed$ make
|
||||
|
||||
