FEATURES
Full-featured evaluation board for the AD7764/AD7765
EVAL-CED1Z compatible
On-board 4.096 V reference
PC software for control and data analysis for
use with EVAL-CED1Z
EVALUATION BOARD DESCRIPTION
This data sheet describes the evaluation board for the AD7764/
AD7765 Σ-Δ ADCs. The AD7764/5 is a 24-bit ADC, serial data
output with multiple decimation rate options incorporating a
full band digital FIR filter. It combines wide input bandwidth
with the benefits of Σ-Δ conversion with a performance of 102/104
dB SNR at 312ksps/156ksps respectively. The AD7764/AD7765
devices are ideal for applications like vibration monitoring,
sonar, and general data acquisition where anti-alias protection
is of importance.
Complete specifications for the AD7764/AD7765 devices are
available in the AD7764/AD7765 data sheets available from Analog
Devices, Inc., and should be consulted in conjunction with this
data sheet when using the evaluation board.
The EVAL-AD7764/AD7765EDZ is controlled using the EVAL-
CED1Z Converter Evaluation and development board. The CED
board outputs the MCLK signal which the AD7764/5 use to
sample the analog inputs.
The AD7764/AD7765 evaluation board interfaces directly with
the FPGA located on the CED board via the SPORT header. The
combination of the EVAL-CED1Z board allied with the EVAL-
AD7764/AD7765/EDZ software allows the user to upload samples
taken by the AD7764/AD7765 device onto a PC showing the
waveform being sampled, as well as allowing the data to be
shown in histogram or FFT format. The EVAL-
AD7764/AD7765/4EDZ can also be used on a standalone basis
(without EVAL-CED1Z); however, in this case the user must
provide the required interface signals.

HARDWARE DESCRIPTION
POWER SUPPLIES
The EVAL-AD7764/5EDZ must be powered using a power supply
that applies a 7.5 V between the V+ and GND terminals of
Connector J2.
This 7.5 V supply is then regulated on board using ADP3330-
2.5 ADP3330-5 devices (U5 and U3) to provide the 2.5 V and 5 V
signals required by the AD7764/AD7765 device.
A filter path of the 2.5 V supply is used to power other digital
functionality on the EVAL-AD7764/AD7765EDZ excluding the
AD7764/AD7765 device. A separately filtered 5 V supply also
supplies the crystal oscillator on the EVAL-AD7764/AD7765EDZ.
The crystal oscillator is provided for customers that wish to use the
device in a stand-alone manner where they wish to provide and
acquire the digital signals going to and from the AD7764/5 device.
For this case, the user may apply the MCLK sourced from the
crystal oscillator. Note that in the default mode the AD7764/5
evaluation board is set up so that the EVAL-CED1Z board
provides the MCLK signal to the ADC as well as providing and
acquiring all other digital signals for the evaluation system.
DIFFERENTIAL INPUT
The differential input to the AD7764/AD7765 device is applied
through the connector marked J1. This is an XLR audio
standard connector. The differential inputs are routed through
the AD7764/AD7765 on-board differential amplifier using the
external circuit components as detailed in the schematic as shown
in this technical note and the AD7764/AD7765 data sheets.
REFERENCE CIRCUIT
The AD7764/5 evaluation board uses the low noise ADR444
(4.096V) reference to supply the ADC. See Gerber files on
AD7764/5 product pages on www.analog.com for details on the
layout and configuration for this reference supply.
STANDALONE OPERATION
The EVAL-AD7764/AD7765EDZ can be used in a standalone
manner (that is, without using the EVAL-CED1Z). In this case,
however, the user must provide all the required interface com-
munications and be able to provide a means to acquire the output.
SMB footprints, allow for external MCLK, SYNC, RESET and
Decimation rate signals to be applied to the AD7764/65 device. All
other digital signals are accessible either from the 34-pin header
(J4) or from the marked test points on the evaluation board.
DECOUPLING AND LAYOUT RECOMMENDATIONS
The data sheets of the AD7764/AD7765 devices contain specific
information about the decoupling and layout recommendations
required to achieve the optimum specifications.
The EVAL-AD7764/AD7765EDZ adheres to these recom-
mendations and is designed as the blueprint for users of the
AD7764/Ad7765 devices.
The EVAL-AD7764/AD7765EDZ are 4-layer boards. One layer
is a dedicated ground plane. All supplies to devices on the
EVAL-AD7764/AD7765EDZ are decoupled to this ground
plane. In addition to the PCB’s top and bottom layers, there is
also a layer for routing power signals. All layers of the board are
detailed in the Evaluation Board Schematic and Artwork
section.

SOFTWARE INSTRUCTIONS FOR NORMAL USE
Once the initial software installation has been completed, follow
these instructions for the general setup of the evaluation software
each subsequent time the system is used.
Note that the hardware must be powered up as per the
Hardware connections section before attempting the following
steps.
1. The download default location for the EVAL-AD7760/
AD7762/AD7763EDZ evaluation software can be found by
clicking Start > All Programs > Analog Devices >
AD7764_5 > AD7764_5. If a location other than the
default was used, follow the path that was entered during
setup.
2. The evaluation software GUI appears.
3. Select the correct AD776x device from the drop down
menu in the top left hand corner of the GUI. i.e. AD7764
for AD7764 evaluation, click AD7765 for AD7765
evaluation.
4. The AD7764/5device under evaluation should power up
automatically when the software is run. Click the Power
Mode drop down menu, and select either ‘Low Power’ or
‘Normal Power’. This will automatically prompt the EVAL-
CED1Z to write to the AD7764/AD7765 registers and set
the power as per your preference for the AD7764/5 device.
5. Note that the external voltage supply connected to the
EVAL-AD7764/AD7765EDZ board will show the current
dropping when you switch between ‘Normal Power’ mode,
‘Low Power mode and “Power Down” mode. Seeing these
current draw levels change, when switching between the
power modes also verifies that the communication
between the EVAL-AD7764/5EDZ and EVAL-CED1Z
boards.
6. The user can specify the power mode, decimation rate, and
number of samples to be acquired (typically 65536
samples) by using the drop-down menus on the software
front panel circled in red in Figure 11. The software allows
the number of samples specified by the user samples to be
viewed as a waveform, histogram, or FFT. The Front panel is
shown in Figure 11.
Figure 11. EVAL-AD7764/AD7765EDZ Evaluation Software
Front Panel Features
EVAL-AD7764/AD7765EDZ Preliminary Technical Data
Rev. PrC | Page 10 of 23
7. For the initial operation of the AD7764 and AD7765 versions
of the evaluation board, set the Decimation Rate to 64 or
128 respectively in the front panel of the AD7764_5
Evaluation Software dialog box. These are the default
decimation rate of the AD7764/
AD7765 parts on reset and power-up of the evaluation board.
8. As well as offering the user different decimation rates the front
panel software also allows the user to select the MCLK
frequency being applied to the AD7764/5 device. Options
include 40MHz, 30MHz, 25MHz, and 20MHz. After selecting
any of these MCLK frequencies, please monitor the MCLK
test point on the evaluation board to ensure the MCLK has
changed in accordance with what you have selected on the
front panel GUI before pressing the Sample or Continuous
buttons to acquire samples.
9. To show samples output by the EVAL-AD7764/5/EDZ
evaluation board Click Sample or Continuous. Clicking
Sample gives one set of samples, the length of which is
determined by the Number of Samples selection on the
software front panel. Clicking Continuous shows
continuously updated samples of the analog input to the
device.
Figure 12. Sample and Continuous Front Panel Buttons
10. It is important to ensure that the frequency of the FSO
pulse on an oscilloscope (at the test-point marked FSO) is
checked so that it matches the frequency shown in the
Frequency text box on the software front panel.
11. If at any stage these do not match, reset the AD7764/AD7765/
evaluation board by pressing the RESET push button on the
evaluation board or using the RESET button on the
software front panel. Then set the decimation rate on the
software front panel to the correct default value.
12. The AD7764/5 software front panel also shows the status
bits corresponding to the final sample in the batch of
samples shown on the screen. The status indicator- marked
“ADC Status Bits” correspond to the final 8 bits output in
each conversion result, and indicate the power mode, over
voltage inputs and Filter Settle information.
13. The AD7764/5 software also allows the user to program
the Overrange and Gain correction registers. The write
functions for these registers are located in the top right
hand corner of the GUI. The default Gain of the AD7764/5
is set to 1.25. Changing this value allows the user to
digitally alter the gain of the conversion result, as it is
output from the AD7764/5 device.
14. Programming the Overrange register allow the user to set a
threshold whereby any signal sampled which passes this
threshold will set off a flag on the overrange bit and
overrange register bit as detailed in the AD7764/5
datasheets.
15. Both of these registers can be read to verify the value
written to the ADC. The Read function and indicator for
each register are located directly below the write functions.
