EVALUATION BOARD HARDWARE
DEVICE DESCRIPTION
The AD7124-4 is a low power, low noise, complete analog front
end for high precision measurement applications. It contains a
low noise, 24-bit, Σ-Δ ADC. It can be configured to have four
differential inputs or seven single-ended or pseudo differential
inputs. The on-chip low noise instrumentation amplifier means
that signals of small amplitude can be interfaced directly to the
ADC. Other on-chip features include a low drift 2.5 V reference,
excitation currents, reference buffers, multiple filter options,
and many diagnostic features.
Complete specifications for the AD7124-4 are provided in the
product data sheet, which should be consulted in conjunction
with this user guide when using the evaluation board. Full details
about the EVAL-SDP-CB1Z are available on the Analog Devices
website.
HARDWARE LINK OPTIONS
Table 1 lists the default link options. By default, the board is
configured to operate from a wall wart (dc plug) power supply
via Connector J5. The supply required for the AD7124-4 comes
from the on-board ADP1720 low dropout regulators (LDOs),
which generate their voltage from J5.

POWER SUPPLIES
SERIAL INTERFACE
The evaluation board requires that an external power supply—
either a bench top supply or a wall wart (dc plug) supply—be
applied to J3 or J5 (see Table 3 for more information). Linear
regulators generate the required power supply levels from the
applied VIN rail. The regulators used are the ADP1720-3.3 (U7)
and the ADP1720 (U4), which supply 3.3 V and 1.8 V,
respectively, to AVDD of the ADC. The 3.3 V ADP1720 (U10)
delivers 3.3 V to the IOVDD pin of the AD7124-4.
The EVAL-AD7124-4SDZ evaluation board connects via the
serial peripheral interface (SPI) to the Blackfin® ADSP-BF527
on the EVAL-SDP-CB1Z. There are four primary signals: CS,
SCLK, DIN, and DOUT/RDY (all are inputs, except for
DOUT/RDY, which is an output).
When a split power supply is used, the AVSS voltage must be
applied from an external source via Connector J9. AVDD and
IOVDD can also be provided via Connector J9. However, the 7 V
to 9 V supply is still required because the on-board reference
(ADR4525) is supplied from this power supply.
Each supply is decoupled at the point where it enters the board
and again at the point where it connects to each device (see the
schematics shown in Figure 26 to Figure 29 to identify
decoupling points).
To operate the EVAL-AD7124-4SDZ in standalone mode, the
AD7124-4 serial interface lines can be disconnected from the
120-pin header by removing the 0 Ω links, R9 through R13. The
test points can then be used to fly-wire the signals to an alternative
digital capture setup.
ANALOG INPUTS
The EVAL-AD7124-4SDZ primary analog inputs can be applied
in two ways:
•
•
Using J6 and J11, the green screw in terminal connectors
Using the A0 and A1 SMB/SMA footprints on the
evaluation board, which connect to the AIN4 and AIN5
analog inputs.
The AD7124-4 EVAL+ Software is set up to analyze dc inputs to
the ADC.

REFERENCE OPTIONS
EVALUATION BOARD SETUP PROCEDURES
The EVAL-AD7124-4SDZ includes an external 2.5 V reference
(the ADR4525) and an internal 2.5 V reference. The default
operation is to use the external reference input, which is set to
accept the 2.5 V ADR4525 on the evaluation board.
After following the instructions in the Software Installation
Procedures section, set up the evaluation and SDP boards as
detailed in this section.
The reference used for a conversion is selected by choosing the
reference in the configuration registers associated with Setup 0

WAVEFROM TAB
Channel Selection
The Waveform tab graphs the conversions and processes the
data, calculating the p-p noise, rms noise, and resolution (see
Figure 21).
The channel selection control (Label 7) chooses which channels
display on the data waveform, and also shows the analog inputs
for the channel labeled next to the on and off controls. These
controls only affect the display of the channels and have no
effect on the channel settings in the ADC register map.
Waveform Graph and Controls
The data waveform graph (Label 1) shows each successive
sample of the ADC output. Zoom in on the data using the
control toolbar (Label 2) in the graph. Change the scales on the
graph by typing values into the x-axis and y-axis.
Analysis Channel
The Noise Analysis section and histogram graph show the
analysis of the channel selected via the Analysis Channel
control (Label 3).
Samples
The Samples numeric control (Label 4) and batch control
(Label 5) set the number of samples gathered per batch and
whether a single batch or multiple batches of samples are
gathered. This control is unrelated to the ADC mode. The user
can capture a defined sample set or continuously gather batches
of samples. In both cases, the number of samples set in the
Samples numeric input dictates the number of samples.
Sample
Click SAMPLE (Label 6) to start gathering ADC results. Results
appear in the waveform graph (Label 1).
Display Units and Axis Controls
Click the Display Units drop-down list (Label 8) to select whether
the data graph displays in units of voltages or codes. 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 sample. When
fixed is selected, the user can program the axis ranges; the axis
ranges do not automatically adjust after each batch of sample.
CRC Error and Overall Error
The CRC Error LED indicator (Label 9) illuminates when
a cyclic redundancy check (CRC) error is detected in the
communications between the software and the AD7124-4. The
CRC functionality on the AD7124-4 is disabled by default and
must be enabled for this indicator to work. The Error Present
LED indicates if an overall error is present in the diagnostics
register. For this indicator to work, the check for the different
diagnostic errors must be enabled in the Error_EN register.
Noise Analysis
The Noise Analysis section (Label 10) displays the results of the
noise analysis for the selected analysis channel, which includes
both noise and resolution measurements.

HISTOGRAM TAB
Display Units and Axis Controls
The Histogram tab generates a histogram using the gathered
samples and processes the data, calculating the peak-to-peak
noise, rms noise, and resolution (see Figure 22).
The data histogram graph (Label 1) shows the number of times
each sample of the ADC output occurs. Zoom in on the data
using the control toolbar (Label 6) in the graph. Change the
scales on the graph by typing values into the x-axis and y-axis.
Click the Display Units drop-down list (Label 4) to select
whether the data graph displays in units of voltages or codes.
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
sample. When fixed is selected, the user can program the axis
ranges; the axis ranges do not automatically adjust after each
batch of sample.
Analysis Channel
CRC Error and Overall Error
The Noise Analysis section and histogram graph show the
analysis of the channel selected via the Analysis Channel
control (Label 2).
The CRC Error LED indicator (Label 5) illuminates when a cyclic
redundancy check (CRC) error is detected, in the communications
between the software and the AD7124-4. The CRC functionality
on the AD7124-4 is disabled by default and must be enabled for
this indicator to work. The Error Present LED (Label 5) indicates
if an overall error is present in the diagnostics register. For this

REGISTER MAP TAB
Use the Register Map tab to access the registers of the AD7124-4.
Figure 23 shows the view when Register Map tab is selected.
This tab can be used to quickly change register settings and also
to obtain additional information about each of the bits in each
of the individual registers.
Register Map
On the left-hand side of Figure 23 are the registers of the
AD7124-4. Click any register to read the register value. Each
register of the AD7124-4 can be accessed quickly using this
register map (Label 1).
Save and Load Buttons
The Save and Load buttons (Label 2) in the Register Map tab
allow the user to save and load register settings. Click Save to
save all the current register settings to a file for use again later.
Click Load to load a previously saved register map.
Register
The Register section (Label 3) shows the value that is currently
set in the selected register. The value of the register can be
checked in this section by clicking the bits that are to be
changed. Clicking any of the individual bit changes that bit
from 1 to 0 or 0 to 1, depending on the initial state of the bit.
The register value can also be changed by writing the hex value
to the input field on the right-hand side of the individual bits.
Bitfields
The individual bitfields of the selected register are shown in the
Bitfields section (Label 4). In this section, the register is broken
by name into its bitfields, name of the bitfields, a description of
each of each bitfield, as well as the access information. The
options for the individual bitfields can be viewed by clicking the
arrow next to the bitfield. Changing the bitfield value can also
be done through this drop-down list. The value of the bitfield
can also be changed by writing the appropriate hex value to the
associated Value input field on the right-hand side of the bitfield.
Documentation
The Documentation section (Label 5) shows information
relating to the different bit fields when selected from the
register map section on the left. This information is the same
information that is presented in the AD7124-4 data sheet.

NOISE TEST—QUICK START DEMONSTRATION
Click the NOISE TEST demo button to configure the device for
the noise test. The AD7124-4 is now configured for the noise test
demo, where the output data rate is set to 9.38 SPS, with the sinc4
digital filter, full power mode of operation, and the REFIN1(±)
external reference selected. Gain and offset are the default factory
values following a reset.
To gather samples, change the Samples field to the number of
samples required value, then click SAMPLE to acquire the
samples from the ADC. Figure 24 shows an example of the
main window after running a noise test.
Reading Samples from the ADC
The evaluation board is set up to use the external 2.5 V on-board
reference (ADR4525). To read samples from the ADC, take the
following steps:
The value in the Refin1(+/-) field on the Configuration
tab is set to 2.5 V by default to use the external 2.5 V onboard reference (ADR4525). If a different reference is used,
set the value in the Refin1(+/-) field accordingly. The
analysis results are based on the value set in this field.
a. When Single Run is selected from the drop-down list,
a batch of samples is read when SAMPLE is clicked,
with the batch size being set by the value in the
Samples box.
Waveform
The waveforms resulting from the gathered samples are shown
in this tab. The waveform graph shows each successive sample
of the ADC output (input referred). The indicators beside this
graph show the channels being converted. Navigation tools are
provided to allow the user to control the cursor, zooming, and
panning. The conversions can be displayed as codes or as volts.
Parameters such as peak-to-peak noise and rms noise are displayed
below the graph in the Analysis section for the current batch of
samples. If several analog input channels are enabled, each enabled
channel can be selected and the conversions on that channel
analyzed using Analysis Channel.
The conversion data can be saved in a text file from the File menu.
To save the data into an Excel file, right-click the waveform graph
and select Export Data from the drop-down list that appears. A
Save dialog box displays, prompting the user to save the data to
an appropriate folder location.
