GENERAL DESCRIPTION
The EVAL-AD7383FMCZ is a fully featured evaluation board
that evaluates all features of the AD7383 analog-to-digital
converter (ADC). The EVAL-AD7383FMCZ is controlled by the
EVAL-SDP-CH1Z (SDP-H1) system demonstration platform
(SDP) via the 160-way SDP connector, J4. The SDP-H1
controls the EVAL-AD7383FMCZ through the USB port of a
PC using the Analysis | Control | Evaluation (ACE) software,
which is available to download from the ACE software page or the
AD7383 product page.
The EVAL-AD7383FMCZ can be used to evaluate the AD7384
(14-bit, 4 MSPS), the AD4682 (16-bit, 1 MSPS), and the AD4683
(16-bit, 500 kSPS) pseudo differential, successive approximation
register (SAR) ADCs. The AD7383 and the AD7384 only differ
in the number of clock cycles when clocking out the conversion
results, which are related to the resolution of the device. The
AD4682 and AD4683 have a slower throughput rate than the
AD7383.
For full details on the AD7383, see the AD7383 data sheet, which
must be consulted in conjunction with this user guide when using
the EVAL-AD7383FMCZ. In addition, full details on the SDP-H1
are available on the SDP-H1 product page, and the comprehensive
ACE user guide is available on the ACE software page.
Figure 1 shows the typical setup of the EVAL-AD7383FMCZ.

EVALUATION BOARD QUICK START GUIDE
The EVAL-AD7383FMCZ is powered by the SDP-H1 by default.
External power supplies can be applied to the EVAL-
AD7383FMCZ. See Table 1 for a description of the optional
external power supply connectors and Table 2 for the required
link option function descriptions. Take the following steps to
evaluate the AD7383:
1. Download and install the ACE software, which is available
on the ACE software page or the AD7383 product page.
Details of the ACE installation are available on the internal
label of the EVAL-AD7383FMCZ box. When installing the
ACE software, ensure that the SDP-H1 is disconnected
from the USB port of the PC. The PC may need to be
restarted after the installation.
2. Ensure that the link options are configured as detailed in
Table 2.
3. Connect the SDP-H1 to the EVAL-AD7383FMCZ, as
shown in Figure 2.
4. Connect the SDP-H1 to the PC via the USB cable. If
prompted by the operating system, choose to automatically
search for the SDP-H1 drivers.
5. Launch the ACE software from the following location:
C:\Program Files (x86)\Analog Devices\ACE.
6. Connect an analog signal to Channel A or Channel B of
the AD7383 via J2 for Channel A and J4 for Channel B.
The AINA− and AINB− inputs are directly connected to
VCM on the EVAL-AD7383FMCZ.

EVALUATION BOARD HARDWARE
EVAL-AD7383FMCZ DESCRIPTION
The EVAL-AD7383FMCZ is an evaluation board for the AD7383,
a 16-bit, dual, simultaneous sampling, high speed, low power,
SAR ADC with a pseudo differential input.
POWER SUPPLIES
Ensure that all link positions are set according to the required
operating mode before applying power and signals to the EVAL-
AD7383FMCZ. See Table 2 for the complete list of link options.
The EVAL-AD7383FMCZ is powered by the SDP-H1 by default.
External power supplies can be applied to the EVAL-
AD7383FMCZ. See Table 1 for a description of the optional
external power supply connectors and Table 2 for the required
link option function descriptions. The EVAL-AD7383FMCZ
has low dropout (LDO) linear regulators (the ADP7182,
ADP7104, and ADP166) that supply power to the AD7383 and
its supporting circuitry, such as the ADA4896-2 amplifiers and
the ADR4533 reference circuit. An external 2.5 V power supply
can also be used with AD7383. The EVAL-AD7383FMCZ has a
footprint ready to place an ADR4525 when an external 2.5 V
power supply is required for evaluation. A pseudo differential
signal can be connected on the Subminiature Version B (SMB)
connectors, J1 to J4.

EVALUATION BOARD SETUP PROCEDURES
The EVAL-AD7383FMCZ connects to the SDP-H1. The SDP-H1
is the communication link between the PC and the EVAL-
AD7383FMCZ. Figure 2 shows a diagram of the connections
between the EVAL-AD7383FMCZ and the SDP-H1.
Connecting the EVAL-AD7383FMCZ and the SDP-H1 to
a PC
After the ACE software is installed, take the following steps to
set up the EVAL-AD7383FMCZ and the SDP-H1.
1. Ensure that all configuration links are in the appropriate
positions, as detailed in Table 2.
2. Connect the EVAL-AD7383FMCZ to the 160-way connector
on the SDP-H1. The EVAL-AD7383FMCZ does not require
an external power supply adapter.
3. To power up the SDP-H1, insert the 12 V, dc barrel jack
(provided in the SDP-H1 kit) into the barrel connector
labeled +12V_VIN on the SDP-H1.
4. Connect the SDP-H1 to the PC via the USB cable included
in the SDP-H1 kit.
Verifying the Board Connection
After connecting the power and the USB cable from the SDP-H1
to the PC, take the following steps to verify the board connection:
1. After connecting the SDP-H1 to the PC, allow the Found
New Hardware Wizard to run. Choose to automatically
search for the drivers for the SDP-H1 if prompted by the
operating system.
2. Navigate to the Device Manager window on the PC
(see Figure 11).
3. A dialog box may open asking for permission to allow the
program to make changes to the computer. Click Yes.
4. The Computer Management window opens. From the list
labeled System Tools, click Device Manager. If the SDP-H1
driver is installed and the board is properly connected to
the PC, Analog Devices SDP-H1 is shown in the ADI
Development Tools list in the Device Manager window,
as shown in Figure 11.
