Analog Devices EVAL-AD4115SDZ User Manual page 12

UG-1820
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
the AD4115 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 AD411x Eval+ software contains a number of demonstration
modes in the Demo Modes area (Label 3 in Figure 16). These
demonstration modes configure the
input types (represented by All Single-Ended and All
Differential).
Reset
Click Reset to perform a software reset of the
in Figure 16). There is no hardware reset pin on the AD4115.
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 AD411x Eval+
information on using the AD411x Eval+
blue + information buttons for further information on different
elements of the Configuration tab.

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 ADR4525. 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 Writing to
Registers During Software Use, 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
can be found at the AD717x/AD411x Mbed Example
