The device only supports a certain number of ODRs. Therefore,
the software rounds up to the closest available value. ODR values
depend on if a single channel or multiple channels are enabled.
The fastest ODRs are available if only one channel is enabled.
The values shown are valid for the sinc5 + sinc1 filter, which is
enabled by default. If the sinc3 filter is enabled instead, refer to
data sheet for the corresponding values.
The value in the
Time(ms)
box represents time taken for one
sample for one enabled channel.
The value in the
Total Time
(ms)
box represents the total time
to take one sample for all enabled inputs.
Demo Modes
The
software contains a number of demonstration
modes in the
Demo Modes
area (Label 3 in Figure 16). These
demonstration modes configure the
for each of the
input types (represented by
All Single-Ended
and
All
Differential
).
Reset

To perform a hard reset, remove power from the EVAL-
AD4115SDZ. The software reset has the same effect as a hard reset.
Tutorial Button
Click the tutorial button (Label 5 in Figure 16) to open a
tutorial on using the
software and for additional
information on using the
software. Click the
blue + information buttons for further information on different
elements of the
Configuration
tab.
Functional Block Diagram
The functional block diagram of the

shows each of the functional blocks within the
Clicking a configuration button on the functional block
diagram opens the configuration window for that block.
Configuration Pop-Up Button
Each + configuration button (Label 7 in Figure 16) opens a
different window to configure the relevant functional block.
External Parameters
There are three external parameters that are set by the EVAL-
AD4115SDZ but must be entered into the software. The three
external parameters are the external reference (Label 8 in
Figure 16), AVDD (Label 9 in Figure 16), and AVSS (Label 10 in
Figure 16). The external reference on the EVAL-AD4115SDZ is
set to 2.5 V by using an
. If bypassing the
on board, change the external reference voltage value in the
software to ensure correct calculation of results in the
Voltage
Waveform
and
Histogram
tabs.
Configuration Summary
Click
Summary
(Label 11 in Figure 16) to show the input
configuration, channel configuration, and information on each
of the individual setups, as well as information on any error
present. The
Input Configuration
,
Channel Configuration
, and
Information
tabs can be used to quickly check how the ADC
inputs and channels are configured, as well as any errors that
are present.
Status Bar
The status bar (Label 12 in Figure 16) displays status updates
such as
Analysis Completed
,
Reset Completed
, and

, as well as the
Busy
indicator.
Save and Load
Save
and
Load
(Label 39 in Figure 20) allow the user to save the
current register map setting to a file and to load the setting from
the same file, respectively. The
Export
button exports the register
settings as a header file that is compatible with the
operating system software drivers
. An example showing how
this configuration file can be used with the
operating system software drivers
to enable rapid prototyping
