EVALUATION BOARD HARDWARE
OVERVIEW
The EVAL-ADAS3023EDZ evaluation board is designed to
offer simple evaluation of this integrated device. From a block
diagram perspective, the board uses a set of analog input test
points (or an IDC header), some passive footprints for RC
filtering and external reference, the ADAS3023 device, a serial
interface to the on-board FPGA, and power that can be
supplied locally or via EVAL-CED1Z or externally. Note that
the ADAS3023 device also has an on-chip reference; however,
external circuitry is provided for those who need to test other
suitable options.
The small prototyping area can be useful for building additional
circuitry, if desired. Each block has a specific function as
defined in the following sections.

Manufactured using the Analog Devices patented high voltage
iCMOS® process, the ADAS3023 is a complete data acquisition
system (DAS) on a single chip that is capable of converting two
channels simultaneously up to 500 kSPS. This part allows the
differential voltage range up to ±20.48 V when using ±15 V
supplies. The ADAS3023 can resolve the full-scale differential
voltages of ±2.56 V, ±5.12 V, ±10.24 V, and ±20.48 V, and it can
be configured to sample two, four, six, or eight channels
simultaneously.
The key difference between the ADAS3022 and ADAS3023
is that the ADAS3023 does not offer the AUX± channels and
temperature sensor (using the CFG register) In addition, the
BUSY/SDO2 (Pin 19) functionality of the ADAS3023 is
different.
The ADAS3022/ADAS3023 devices become pin compatible
and can be exchanged on the same footprint if the no connect
(NC) pins (Pin 14/Pin 29/Pin 30 on the ADAS3022) and AUX±
(Pin 5 and Pin 40 on the ADAS3022) are tied to AGND, and if
the SDO2 (using the CFG register) of the ADAS3023 is not
enabled, so that the user can actually work with either one of
these options using the same evaluation board. Leaving these
pins floating is not recommended. Note that the differential
paired mode does not exist in the ADAS3023 and, therefore, its
2/4/6/8 channels are always referenced to COM.
The ADAS3023 is an ideal replacement for a typical 16-bit,
simultaneous sampling precision data acquisition system that
simplifies the design challenges by eliminating signal buffering,
level shifting, amplification/attenuation, common-mode
rejection, settling time, or any of the other analog signal
conditioning challenges while allowing smaller form factor,
faster time to market, and lower costs.
Data communication to and from the ADAS3023 occurs
asynchronously without any pipeline delay using a common
4-wire serial interface compatible with SPI, FPGA, and DSP.
A rising edge on CNV samples the differential analog inputs of
a channel or channel pair. The ADAS3023 configuration register
allows the user to configure the number of enabled channels, the
differential input voltage range, and the interface mode using the
evaluation board and software as detailed in this user guide.
Complete specifications for the ADAS3023 are provided in the
product data sheet and should be consulted in conjunction with
this user guide when using the evaluation board. Full details on
the EVAL-CED1Z are available on the Analog Devices website.

JUMPERS, SOLDER PADS, AND TEST POINTS
Numerous solder pads and test points are provided on the
evaluation board and are detailed fully in Table 4, Table 5,
and Table 6. Note the nomenclature for this evaluation board
for a signal that is also connected to an IDC connector would
be signal_I. The two 3-pin user selectable jumpers are used for
the ADCs reference selection and are fully described in the
Reference section.
ANALOG INTERFACE
The analog interface is provided with test points for each of the
analog inputs IN[7:0] and COM (that is, IN0_I is common to
both the test point and to P1). The passive device footprints
can be used for filtering, if desired. A simple RC filter made up
of 22 Ω and 2700 pF NPO capacitors is provided. Note that
the use of stable dielectric capacitors, such as NPO or COG, is
required in the analog signal path to preserve the ADAS3023
distortion. Using X5R or other capacitors in the analog signal
path greatly reduces the performance of the system. Also, note
that many bench top arbitrary waveform generators (AWGs)
use 12-bit or 14-bit digital-to-analog converter outputs such
that the 16-bit ADAS3023 devices digitize this directly resulting
in erroneous looking data. If such an AWG is used, a high-order
band-pass filter should be used to filter the unwanted noise
from these sources.
The P31 center pin is connected to the ADAS3023 COM input,
which can be routed to P1 or GND using P31. For channel
‐to‐
COM configuration, set the jumper across Pin 1 and Pin 2 to
route to P1. For channel pairs configuration, set the jumper
across Pin 2 to Pin 3 to route to GND. This is useful for singleended applications.
For dynamic performance, an FFT test can be done by applying
a very low distortion ac source, such as an Audio Precision
System 2702. This source can be set for balanced or unbalanced,
and can be floated or grounded depending on the user’s choice.

FPGA
The on-board FPGA performs a number of digital functions,
one of them being the sample rate conversion controlled
using the software. Another function is deserializing the
serial conversion results as the CED data capture board uses
a 16-bit parallel interface. If desired, the deserialized data can
be monitored on the 96-pin edge connecter P1, BD[15:0].
The CED uses a buffered busy signal, BBUSY, as the general
interrupt for the data transfer to the CED board.

factory default setting.

The connection is made through R102 = 10 k to GND.
To use another reference source, there are two methods:
The FPGA also provides the necessary ADAS3023 asynchronous control signals for RESET and power down (PD).
•
For an external unbuffered reference, remove the P9
jumper and connect a source to the REF test point.
The signals from the FPGA to the ADAS3023 can be bypassed
by modifying the default solder pad connections. As shown in
Figure 2, each digital signal on the ADAS3023 is connected to
the larger (top) pad of the three. The default configuration is
the small pad and larger pad (no text) which connects the
FPGA to the ADAS3023 (CNV, BUSY, and SDO signals
shown). The labeled pads, CNV_I, BUSY_I, SDO_I, and so on,
are the signals that are routed to P3. To use P3 instead of the
FPGA, unsolder the default connections and resolder from the
large pad to the xxx_I pads. The FPGA will remain powered;
however, if all the signals are bypassed in this fashion, it will not
have any influence on the ADAS3023.
•
Since the ADR434 is a standard 8-lead SOIC, it can also
be removed and replaced with the user’s reference. In this
case, the user reference and the U20 AD8032 buffer can
be used as a reference source.
DEFAULT
Internal 4.096 V Reference
The ADC has an internal 4.096 V precision reference and
can be used on most applications. When enabled, 4.096 V will
be present on the ADAS3023 REFx pin and test point, REF.
In addition, a voltage will also be present on the ADAS3023
REFIN pin and test point, REFIN. The voltage present on
REFIN can be used for other purposes, such as to provide the
bias voltage; however, it would need a suitable buffer as the
output impedance of the REFIN is on the order of a few kilo
ohms and loading this voltage down will degrade the internal
reference’s performance.

Note that the ADAS3023 configuration register needs to be

Serial Interface
The 4-wire serial interface consisting of CS, DIN, SCK, and
SDO is present on the digital interface test points and is
controlled by the FPGA. The FPGA can be bypassed by using
the solder pads.
REFERENCE
The ADAS3023 has an internal 4.096 V reference, along with an
internal buffer, useful for using an external reference or one can
use an external 4.096 V reference directly, such as the ADR434
provided on the evaluation board. The evaluation board can be
configured to use any of these references. Two jumpers (P5
and P7) are used for setting the reference in conjunction with
software control.
External Reference–Factory Configuration
The evaluation board includes the ADR434, A1, which is a
4.096 V precision voltage reference. This reference can drive
the ADC REF1 or REF2 (REFx) pin directly or it can also be
Jumper
Internal Reference Buffer
The internal reference buffer is useful when using an external
2.5 V reference. When using the internal reference buffer,
applying 2.5 V to REFIN, which is directly connected to the
ADC’s REFIN pin, produces 4.096 V at the ADCs REFx pin
and REF test point.
POWER SUPPLIES AND GROUNDING
The on-board ADP3334 low dropout regulators are provided
for 2.5 V, 3.3 V, and 5 V and also for the FPGA I/O supply
which is user configurable and set to 3.3 V by default. The
FPGA core is supplied by a pair of ADP1715 devices set for
1.2 V. Additional power is supplies via the CED board for an
alternative +5 V analog and digital 3.3 V/5 V digital through P4.

Figure 3 shows a photograph of the connections made between
the ADAS3023 daughter board and the EVAL-CED1Z board.
The ADAS3023 requires ±15 V supplies for VDDH and VSSH.
These must be supplied by the user using a standard lab supply
ensuring that the return paths are at the same potential. Refer to
CN-0201 for the complete information on generating these
±15 V supplies from a +5 V single supply. The differential input
common-mode voltage (VCM) range changes according to the
maximum input range selected and the high voltage power
supplies (VDDH and VSSH). In other words, the specified
operating input voltage of any input pin requires 2.5 V of
headroom from the VDDH and VSSH supplies.

The evaluation board ground plane consists of a solid plane
on one PCB layer shared on another layer with the power plane.
To attain high-resolution performance, the board was designed
to ensure that all digital ground return paths do not cross the
analog ground return paths, that is, all analog on one side and
digital on the other.

EVALUATION BOARD SCHEMATICS/PCB LAYOUT
The evaluation board is a 6-layer board carefully laid out and
tested to demonstrate the specific high accuracy performance
of the ADAS3023 devices. The Evaluation Board Schematics
and Artwork section of this user guide shows the schematics of
the evaluation board.
Before connecting power, ensure that the EVALADAS3023EDZ and the EVAL-CED1Z boards are
connected firmly together.
Connect the power supplies on the EVAL-ADAS3023EDZ
board. The EVAL-ADAS3023EDZ requires external power
supplies of ±15 V. Connect them from a bench top power
supply.
Connect the EVAL-CED1Z board to the PC via the USB
cable enclosed in the EVAL-CED1Z kit. If using a
Windows® XP platform, you may need to search for the
EVAL-CED1Z drivers. Choose to automatically search for
the drivers for the EVAL-CED1Z board if prompted by the
operating system.
Proceed to the Software Installation section to install the
software. Note that the EVAL-CED1Z board must not
be connected to the PC’s USB port until the software is
installed. The 7 V dc supply can be connected, however,
to check that the board has power (green LED lit).
BASIC HARDWARE SETUP
The ADAS3023 evaluation board connects to the EVAL-CED1Z

Start Up
Refer to the numbered labels in Figure 18. Click the blue
buttons to reveal the dialog boxes shown in Figure 19 through
Figure 23.
To begin evaluating the device, the on-board supplies must be
enabled.
•
•
•
•
•
RESET resets the ADAS3023 device to a known state.
Click RESET twice: once to reset the ADAS3023 and
again to bring it out of the reset state. Note that the
CFG is also reset to the default condition.
Reference Selection: At this time, it is recommended
to use the evaluation board’s externally generated
reference (default). To select the on-chip reference,
remove the P5 and P7 jumpers and click the button in
the REF block to display the Reference Settings
dialog box, then choose REFERENCE ENABLED.
PD (0) places the ADAS3023 device in power-down.
This does not need to take place when starting the
software.
Serial Data Output 2 (SDO2) Option: The ADAS3023
busy signal is always output on the BUSY/SDO2 pin
when CS is logic high. If SDO2 is enabled when CS is
brought low after the EOC, the SDO outputs the data
from Channel 0, Channel 1, Channel 2, and Channel 3
and SDO2 outputs the data from Channel 4, Channel 5,
Channel 6, and Channel 7 after 16 SCK rising edges.
The conversion result output on this pin synchronizes
to the SCK falling edges. Click SDO2 DISABLED
once to display SDO2 ENABLED.
Click OK: If the default configuration (number of
channels, PGIA, reference, and SDO2 settings) is
acceptable, clicking OK writes to the ADAS3023
configuration register (CFG). The ADAS3023 device
is configurable using a 16-bit on-chip register, CFG
(refer to the ADAS3023 data sheet for more details).
Note that after changing any of the CFG register
settings, OK button must be clicked for the new
setting to take effect.
Input Channel
To select the number of input channels to be simultaneously
sampled, make a selection from the pull-down menu. (see
Figure 19).
Programmable Gain
The most useful and innovative feature of the ADAS3023 is the
on-chip programmable gain instrumentation amplifier. This
amplifier has the added flexibility of allowing for inputs ranging
from ±2.56 V to ±20.48 V. Select the appropriate setting for the
input voltage span, not including any common-mode signals,
since they are rejected. Note that the ADAS3023 devices do not
need the usual level shifting that is common in SAR ADC
systems. The ADAS3023 devices can accommodate singleended unipolar and bipolar input signal types.
Software Controls
Within any of the chart panels, these controls are used to
control the display.

TIME DOMAIN TAB
11221-224
Figure 24 illustrates the Time Domain tab. The ADAS3023
output is twos complement output; however, the software
outputs the results in straight binary.
Note that Label 1 shows the Waveform Analysis that reports
the amplitude recorded from the captured signal in addition to
the frequency of the signal tone, and Label 2 shows that Y-axis
units can be displayed in volts or code (LSB).

HISTOGRAM TAB
The histogram is most often used for dc testing or ac testing,
where a user tests the ADC for the code distribution for dc input
and computes the mean and standard deviation, or transition
noise, of the converter, and displays the results. Raw data is
captured and passed to the PC for statistical computations.
Figure 25 shows the Histogram tab.
To perform a histogram test,
1.
Select the Histogram tab.
2.
Click Single Capture or Continuous Capture.
DC Testing
filter the signal to make the dc source noise compatible with
that of the ADC. Note that 0805 and 0603 SMT pads are
provided in each signal path and can be used for filtering the
source, if necessary.
AC Testing
Figure 25 shows the histogram for a 1 kHz sine wave applied to
the analog inputs IN[7:0]_I via test points or P1 from a quality
precision signal source, such as Audio Precision. It may be
required to filter the input signal from the ac source. There is no
suggested band-pass filter, but consider all choices carefully.
The Waveform Analysis (Label 1) chart displays the various
measured histogram values for the ADAS3023.
11221-225
To test other dc values, apply a source to the selected analog
inputs IN[7:0]_I via test points or P1. It may be required to

SPECTRUM TAB
Figure 26 shows the FFT spectrum capture tab. This tab tests
the traditional ac characteristics of the converter and displays a
fast Fourier transform (FFT) of the results. As in the histogram
test, raw data is captured and passed to the PC where the FFT is
performed, displaying SNR, SINAD, THD, and SFDR.
•
•
The top part of the image displays the FFT results
including SNR, dynamic range, THD, SINAD, and noise
performance (see Label 1).
The lower part of the image displays the fundamental
frequency and amplitude in addition to the 2nd to 5th
harmonics (see Label 2).
11221-226
To perform an ac test, apply a sinusoidal signal to the evaluation
board to any pair of the analog inputs IN[7:0]_I, either via test
points or P1. Very low distortion—a better than 130 dB input
signal source, such as Audio Precision)—is required to allow
true evaluation of the part. One possibility is to filter the input
signal from the ac source. There is no suggested band-pass
filter, but carefully consider the choices. Figure 26 displays the
results of the captured data.
