+=================

4+
+By default, the device_name parameter in the class constructor is the
5+
+same as the class name. To use the class with another supported model,
6+
+the name must be given when instantiating the object. For example, if
7+
+working with an ad7626 with a URI of "10.2.5.222", use the ad7625 class,
8+
+but specify the device_name parameter explicitly:
9+
+
10+
+.. code-block:: bash
11+
+
12+
+ import adi
13+
+ adc = adi.ad7625(uri="ip:10.2.5.222", device_name="ad7626")
14+
+ ...
15+
+
16+
+
17+
+.. automodule:: adi.ad7625
