GENERAL DESCRIPTION
The E VA L -AD7386FMCZ is a full featured evaluation board
designed to evaluate all the features of the AD7386 analog-to-
digital converter (ADC). The evaluation board can be controlled by
the E VA L-SDP-CH1Z via the 160-way system demonstration
platform connector, P7. The E VA L -SDP-CH1Z board controls
the evaluation board through the USB port of the PC using the
Analysis Control Evaluation (ACE) software, which is available
for download from the ACE software page.
The EVAL-AD7386FMCZ can evaluate the AD7387 and
AD7388 by using the AD738x ACE plugin found on the EVAL-
AD7386FMCZ product page. The only difference is the number
of SCLKs that clock out the conversion results, which is dependent
on the resolution for each generic.
Complete specifications for the AD7386/AD7387/AD7388 are
provided in the AD7386/AD7387/AD7388 data sheet. Consult
these specifications in conjunction with this user guide when
using the evaluation board. Full details on the E VA L -SDP-CH1Z
are available on the SDP-H1 product page. The comprehensive
ACE user guide is available on the ACE software page.

QUICK START GUIDE
The E VA L -AD7386FMCZ is powered by the E VA L-SDP-CH1Z
board by default. External power supplies can be applied. See
Table 1 for a description of connectors and Table 2 for the link
configuration required. Use the following steps to evaluate the
AD7386:
1. Download and install the ACE evaluation software,
available on the AD7386 product page. Details of this
installation are available on the evaluation board box
internal label. Ensure that the EVA L-SDP-CH1Z board is
disconnected from the USB port of the PC while installing
the software. The PC may need a restart after installation.
2. Ensure that the link options are configured as detailed in
Table 2.
3. Connect the E VA L -SDP-CH1Z board to the EVAL-
AD7386FMCZ, as shown in Figure 2.
4. Connect the E VA L -SDP-CH1Z board to the PC via the
USB cable. If using Windows® XP, search for the E VA L -
SDP-CH1Z drivers. Choose to automatically search for the
drivers for the E VA L-SDP-CH1Z board if prompted by the
operating system.
5. Copy the ACE plugins file, Board.AD738x, and the
Chip.AD738x folder from the FTP site to the
C:\ProgramData\Analog Devices\ACE\Plugins folder.
6. Launch the ACE evaluation software from the ACE
subfolder in the Analog Devices folder in the All
Programs menu.
7. Connect an input signal to the AINA0, AINA1, AINB0, or
AINB1 channel.

EVALUATION BOARD HARDWARE
AD7386 DESCRIPTION
The AD7386 is a 16-bit dual, simultaneous sampling, high
speed, low power, successive approximation ADC and features a
throughput rate of 4 MSPS. The analog input type is differential.
The AD7386 can accept a wide common-mode input voltage
and is sampled and converted on the falling edge of CS.
The AD7386 has an optional integrated, on-chip, oversampling
block to improve dynamic range and reduce noise at lower
bandwidths. An internal 2.5 V reference is included.
Alternatively, an external reference up to 3.3 V can be used.
The conversion process and data acquisition use standard control
inputs, allowing easy interfacing to microprocessors or digital
signal processors (DSPs). The AD7386 is compatible with 1.8 V,
2.5 V, and 3.3 V interfaces, using the separate logic supply.
The AD7386 is available in a 16-lead LFCSP with operation
specified from −40°C to +125°C.
POWER SUPPLIES
The EVAL-AD7386FMCZ operates from a 12 V power supply.
Ensure that all link positions are set according to the required
operating mode before applying power and signals to the
E VA L-AD7386FMCZ. See Table 2 for the complete list of link
options.
The EVAL-AD7386FMCZ is powered by the E VA L -SDP-CH1Z
board by default. External power supplies can be applied to the
board. See Table 1 for a description of the connectors used and
Table 2 for the link configurations required.

EVALUATION BOARD CIRCUITRY
SOCKETS AND CONNECTORS
The connectors and sockets on the EVAL-AD7386FMCZ are
described in Table 3.
The default interface to the EVAL-AD7386FMCZ is via the 160-
way connector, which connects the E VA L -AD7386FMCZ to the
E VA L-SDP-CH1Z. If using the E VA L -AD7386FMCZ in
standalone mode, communication is achieved via the P3
header pins.
TEST POINTS
There are several test points and single in line (SIL) headers on
the EVAL-AD7386FMCZ. These test points provide easy access
to the signals from the evaluation board for probing, evaluation,
and debugging.
