EVALUATION BOARD HARDWARE
DEVICE DESCRIPTION
HARDWARE LINK OPTIONS
The AD7175-8 is a highly accurate, high resolution, multiplexed,
8-/16-channel (full/pseudo differential) Σ-Δ ADC. The AD7175-8
has a maximum channel-to-channel scan rate of 50 kSPS (20 µs)
for fully settled data The output data rates range from 5 SPS to
250 kSPS. The device includes integrated analog input and
reference buffers, an integrated precision 2.5 V reference, and
an integrated oscillator.
See Table 1 for the default link options. By default, the board is
configured to operate from the supplied 9 V ac-to-dc adapter
connected to Connector J4. The 5 V supply required for the
AD7175-8 comes from the on-board low dropout regulator
(LDO). The ADP1720, with a 5 V fixed output voltage, receives
its input voltage from J2 or J4 (depending on the position of LK2)
and generates a 5 V output.

SERIAL INTERFACE
POWER SUPPLIES
The EVAL-AD7175-8SDZ evaluation board connects to the
Blackfin® ADSP-BF527 on the SDP-B controller board via the
serial peripheral interface (SPI). There are four primary signals,
CS, SCLK, and DIN (all inputs), and one output from the ADC,
DOUT/RDY.
Power the evaluation board from the ac-to-dc adapter
connected to J4, or from an external bench top supply applied
to J3 or J5. Linear LDOs generate the required voltages from the
applied input voltage (VIN) rail when using J3 or J4. Use J5 to
bypass the on-board regulators. The regulators used are the 5 V
fixed output voltage and 2.5 V adjustable output voltage
ADP1720 devices, which supply the AVDD1 and AVDD2 rails
to the ADC; the ADP1720 (3.3 V) supplies the IOVDD rail. Use
the ADP7104 (5 V) to supply 5 V for the SDP-B controller
board. Each supply is decoupled where it enters the board and
again at each device. Table 3 shows the various power supply
configurations available, including split supply operation.
To operate the evaluation board in standalone mode, disconnect
the AD7175-8 serial interface lines from the 120-pin header by
removing the 0 Ω, R9 through R13 links. Use the test points to
connect the signals to an alternative digital capture setup.

information on using the AD717x Eval+ software.
These input fields are used to take the supply voltage levels
selected for the AD7175-8. Checks are performed to ensure the
power supply voltage levels entered are within the specified
limits. These power supply voltage levels are also used for the
modelled performance to calculate the power dissipation.
External Reference (Ext. REF) (8)
The Ext. REF input fields set the positive and negative external
reference voltage values. The difference is used for calculating
the results for both the Waveform and Histogram tabs. The
evaluation board has an external 5 V ADR445 reference, which
can be bypassed by removing R32. Change the external
reference values in Ext. REF to ensure correct calculation of
results in the Waveform and Histogram tabs.

Click the Reset ADC button to perform a software reset of the
AD7175-8 . The AD7175-8 does not have a hardware reset pin,
to perform a hard reset the power must be removed from the
board. The software reset has the same effect as a hard reset.
Menu Bar (11)
performs the same action as the Select Product button and
Reset ADC performs the same action as the Reset ADC button.
Help
The Help drop-down menu provides links to extra information
about the AD7175-8 , which includes links to the AD7175-8
product page, EVAL-AD7175-8SDZ evaluation board user
guide, AD7175-8 datasheet, and No-OS Drivers. Selecting the
AD717x Eval+ Tutorial opens the tutorial outlined in the
Tutorial Button (3) section. For details on the current version of
the software the About option opens a dialog box displaying the
current version of the software and relevant licenses.
Status Bar (12)
The menu bar has three section: File, Edit, and Help.
File
There are three options available in the File drop-down menu:
Save, Load, and Generate.
SAVE
Save allows the user to save register configurations or waveform
data. Register configurations can be saved as a JSON file or a
header file. If the configuration is only used in the AD717x
Eval+ software environment then it is recommended to use the
JSON setting. Waveforms are saved as .csv files and the user is
prompted to save the register configuration as well.
LOAD
Load allows the user to load saved register configurations or
waveform data. In order to load a header into AD717x Eval+ it
must be in the same format as one that is saved from AD717x
Eval+. The header file can be used when developing firmware.
When loading the waveform data the user is prompted to load
the register configuration. This allows the software to correctly
analyze the data.
The status bar displays the busy indicator and status updates,
such as Analysis Completed and Reset Completed during
software use.
Device Error (13)
The Device Error LED icon illuminates when an ADC error is
detected or when a cyclic redundancy check (CRC) error occurs.
The CRC functionality on the AD7175-8 is disabled by default
and must be enabled for the Device Error indicator to work.
Specific information on the error can be found in the Register
Configuration Summary(9) section.
External MCLK Frequency (15)
This field sets the external MCLK frequency. External MCLK
Frequency (15)] is only visible on the front panel when an
external clock source is selected by the ADC. It is used by the
functional model for modelled performance.
Analog Input Voltage (16)
These fields are only available when simulation mode is
selected.These inputs allow the analog input voltages to be set
and can be changed at any time while in simulation mode.
External SCLK Frequency (17)
Edit
There are two options in the Edit drop-down menu; Change
Product Selection and Reset ADC. Change Product Selection
This input field sets the external SCLK frequency for the SPI
interface. This field is only available in simulation mode to
determine if the SCLK frequency is within the permitted range.

WAVEFORM TAB (18)
Channel Selection (24)
Figure 18 shows the Waveform tab of the AD717x
Eval+Software.
The channel selection control allows the user to choose which
channels display on the data waveform graph (23). These controls
only affect the display of the channels and have no effect on the
channel settings in the ADC register map.
Sampling Mode (19)
This control is unrelated to ADC mode. The user can capture a
defined sample set, single capture; or continuously gather
batches of samples, repeated capture. The user can also select
data logging that runs similar to repeated capture, but posts the
results to a .csv file. When saving, the .csv file prompts the user
to save the register configuration. This is necessary to load the
data back into the software for analysis.
Samples (20)
The Samples field control sets the number of samples gathered
per batch. Single capture returns the number enters into the
Samples control. Repeated capture keeps returning batches of
the number entered into the Samples control until stopped by
the user.
Sample (21)
Click the Sample button to start gathering ADC results. Results
appear in the waveform graph (22). See Figure 18.
Waveform Graph and Controls (22 and 23)
The data waveform graph shows each successive sample of the
ADC output. Zoom in on the data using the control toolbar
(labeled 23 in Figure 18). Click the x-axis and y-axis to change
the scales on the graph.
Noise Analysis (25)
The Noise Analysis section displays the results of the noise
analysis for the selected analysis channel, which includes both
noise and resolution measurements.
Analysis Channel (26)
The Noise Analysis section and histogram graph show the
analysis of the channel selected via the Analysis Control dropdown menu.
Display Units and Axis Controls (27)
Click the Display Units drop-down menu to select the unit
displayed in the graph. This control affects both the waveform
graph and the histogram graph. The axis controls can be
switched between dynamic and fixed. When dynamic is
selected, the axis automatically adjusts to show the entire range
of the ADC results after each batch of samples. When fixed is
selected, the user can program the axis ranges; the axis ranges
do not automatically adjust after each batch of samples.
