GENERAL DESCRIPTION
The AD4000/AD4001/AD4002/AD4003/AD4020 family of
evaluation boards enable quick, simplified evaluation of the
AD4000 family of 16-/18-/20-bit, precision successive approximation register (SAR) analog-to-digital converters (ADCs). The
AD4000/AD4001/AD4002/AD4003/AD4020 are low power,
16-bit/18-bit/20-bit, precision SAR ADCs that offer high
performance with throughputs up to 2 MSPS (1.8 MSPS for the
AD4020). The evaluation board demonstrates the performance of
the AD4000/AD4001/AD4002/AD4003/AD4020 family of

ADCs and provides a simplified interface for a variety of system
applications.
The EVAL-AD4000FMCZ/EVAL-AD4001FMCZ/EVALAD4002FMCZ/EVAL-AD4003FMCZ/EVAL-AD4020FMCZ
evaluation boards, accessible from the EVAL-AD400x-FMCZ
product page, (see Figure 1) are ideal for use with the Analog
Devices, Inc., high speed system demonstration platform (SDPH1). These evaluation boards interface to the SDP-H1 board via
a field-programmable gate array (FPGA) mezzanine card
(FMC) low pin count (LPC) connector.
On-board components include a high precision buffered band
gap 5.0 V reference (ADR4550), a reference buffer (ADA4807-1),
a common-mode buffer (ADA4807-1), a signal conditioning
circuit with two op amps (ADA4807-1), and a power supply to
derive the necessary voltage levels to supply all voltage needs.
The EVAL-AD4000FMCZ, EVAL-AD4001FMCZ, EVALAD4002FMCZ, EVAL-AD4003FMCZ, and EVALAD4020FMCZ are populated with the AD4000, AD4001,
AD4002, AD4003, and AD4020, respectively. However, these
boards can be used to evaluate the performance of the AD4004,
AD4005, AD4006, AD4007, AD4008, AD4010, AD4011,
AD4021, and AD4022 by limiting the sample rate in the evaluation
software to the maximum sample rate of the specific ADC.
For example, the AD4000 on the EVAL-AD4000FMCZ can be
used to evaluate the performance of the AD4004 if the sample
rate is limited to 1 MSPS. See the data sheet of each product for
the corresponding evaluation board.
Full descriptions of these products are available in their
respective data sheets, which must be consulted when using the
corresponding evaluation board. Table 7 shows the models of
the AD4000/AD4001/AD4002/AD4003/AD4020 evaluation
boards.

SETTING UP THE EVALUATION BOARD
Figure 2 shows the simplified evaluation board block diagram.
Figure 24 shows the evaluation board schematic. The board
consists of the ADC, U1, with a reference, U6 (ADR4550), and
ADC drivers, U12 and U14, the ADA4807-1 for the AD4001/
AD4002/AD4003/AD4020, and the ADA4805-1 for the
AD4000 (see Table 6). The user also has an option to populate
U2 with a low power, fully differential ADC driver, such as the
ADA4940-1, when evaluating the AD4001/AD4003/AD4020.
The evaluation board is a flexible design that enables the user to
select components in addition to operating from an adjustable
bench top power supply.
Each supply is decoupled where it enters the board and at each
device. A single ground plane is used on this board to minimize
the effect of high frequency noise interference.
In addition, the board can be powered from a benchtop power
supply. The screw terminals, J2 and J3, are provided for this
function. When bench power is used, the on-board power
supplies are no longer required. The solder links also must be
changed as follows: SL1 = SL2 = SL5 = SL6 = SL7 = SL8 = SL9 = B.

POWER SUPPLIES
An external 5 V reference (U6, ADR4550) is used by default to
supply the ADCs directly. The user can also use one of the 2.5 V,
3.3 V, and 4.096 V references by changing the on-board reference
device U6 (ADR4525/ADR4533/ADR4540). There is an option to
use a lower power reference, U22 (ADR3450). Note that the
ADR3450 cannot accept input voltages beyond 5.5 V. The
ADA4807-1 is used as a reference buffer (U16) and common-mode
buffer (U18) by default. However, U16 can also be replaced by
the AD8031 if required without compromising the
performance.
Identifying the Evaluation Board
The system demonstration platform (SDP-H1) board supplies
12 V to power the necessary rails for the EVAL-AD400x-FMCZ
evaluation boards.
The 7 V amplifier positive rail (+VS) is generated from U17
(ADP7118). The −2.5 V negative amplifier rail (−VS) is
generated by a combination of U3 (ADP2370), U7 (ADM660),
and U21 (ADP7182).

SDP-H1 CONTROLLER BOARD
SOLDER LINKS
The evaluation board uses a serial port interface (SPI) and is
connected to the system demonstration platform (SDP-H1)
controller board. The SDP-H1 board requires power from a 12 V
wall adapter (included with the SDP-H1). The SDP-H1 has a
Xilinx® Spartan 6 and an ADSP-BF527 processor with connectivity
to the PC through a USB 2.0 high speed port. The SDP-H1
allows the configuration and capture of data on the evaluation
boards from the PC via USB.
The three solder link options on the evaluation board are
configured depending on the generic of the ADC on the
specific evaluation board, as described in Table 3.
The evaluation board supports any amplifier mezzanine card
(AMC). Insert this add on card on the 7-pin headers. Figure 3
shows the AMC mounted on the evaluation board. The AMC
ADC driver settings are required to use this option, described
in Table 4.
14981-103
The SDP-H1 has an FMC LPC connector with full differential low
voltage differential signaling (LVDS) and singled-ended low voltage
complementary metal-oxide semiconductor (LVCMOS) support.
The SDP-H1 also has a 120-pin connector that exposes the
Blackfin® processor peripherals. This connector provides a
configurable serial, parallel I2C and SPI, and general-purpose
input/output (GPIO) communications lines to the attached
daughter board.

ANALOG INPUTS
The analog inputs to the evaluation board are SMA connectors,
J6 and J10. These inputs are buffered with dedicated amplifier
circuitry (U12 and U14), as shown in Figure 26. The circuit
allows different configurations, input range scaling, filtering,
addition of a dc component, and use of different op amp and
supplies. The analog input amplifiers are set as unity-gain
buffers at the factory.
The optional fully differential amplifier (FDA) can be used with the
fully differential AD4000 devices on the EVAL-AD4001FMCZ,
EVAL-AD4003FMCZ, and EVAL-AD4020FMCZ boards. Table 2
lists the necessary jumper positions for using the FDA (U2).
The AD4000 family devices require the inputs to be biased at
midscale. The default configuration also sets both U12 and U14
at midscale, generated from a buffered reference voltage divider
(VCM). The noninverting inputs of both U12 and U14 are
connected to the 590 Ω resistor dividers by default. These resistor

dividers, R27, R28, R34, and R35, divide the reference voltage in
half. The 590 Ω resistor dividers must be taken into account when
interfacing with an external source via J6 and J10. The FDA
(U2) outputs are biased to midscale with a 10 kΩ resistor
divider (R65 and R67).
The EVAL-AD400x-FMCZ evaluation boards are factory
configured to provide the appropriate input signal type, singleended or fully differential, with the SL4 link. See Table 2 and
Figure 26 for more information.
To evaluate dynamic performance, a fast Fourier transform
(FFT) test can be performed by applying a very low distortion
ac source.
For low frequency testing, the audio precision source (such as the
SYS-2700 series) can be used directly because the outputs on these
are isolated. Set the outputs for balanced and floating ground.
Different precision sources can be used with additional filtering.

TROUBLESHOOTING
SOFTWARE
HARDWARE
To troubleshoot the software, take the following steps:
To troubleshoot the hardware, take the following steps:
1.
1.
2.
3.
4.
5.
Always install the software before connecting the hardware to
the PC.
Always allow the install to fully complete (the software is a
two-part installation, the ADC evaluation software and the
SDP-H1 drivers). A restart is recommended after installation
is finished.
When the user first plugs in the SDP-H1 board via the
provided USB cable, allow the Found New Hardware
Wizard to run, which can take several seconds. However,
allow this to happen before starting the software.
If the EVAL-AD400x-FMCZ evaluation boards or SDP-H1
board are connected to the PC via the USB port but are not
being detected by the AD40XX Evaluation Software
Installer, ensure that the board is being recognized in the
Device Manager, as shown in Figure 16.
If connected to a slower USB port where the SDP-H1 cannot
read as quickly as it needs to, a timeout error can result. In
this case, it is advised not to read continuously, or
alternatively, to lower the number of samples taken.
2.
Rev. I | Page 20 of 30
If the software does not read back any data, do the following:
a. Check that the power is applied within the power
ranges described in the Power Supplies section.
b. Using a voltmeter, measure the voltage present at each
of the test points: +VS, −VS, 1P8V_VDD, VDD_1P8V,
+3P3V, +5V, and REF1, and common-mode voltages
(REF/2) at IN+ and IN− to ensure that they are accurate.
The SDP-H1 board LED1 must be illuminated.
c. Launch the software and read the data. If nothing
happens, exit the software.
d. Power down the board and relaunch the software.
e. If no data is read back, confirm that the ADC evaluation
board is connected to the SDP-H1 board and that the
board is being recognized in the Device Manager, as
shown in Figure 16.
When the user is working with the software in standalone/
offline mode (no hardware connected) and later chooses to
connect hardware, close and relaunch the software.
