EVALUATION BOARD HARDWARE
DEVICE DESCRIPTION
This user guide describes the evaluation board for the
AD7091R analog-to-digital converter.
The AD7091R is a 12-bit, ultralow power, successive approximation ADC. The AD7091R operates from a single 2.7 V to 5.25 V
power supply and is capable of achieving a throughput rate of
1 MSPS. The AD7091R also features an on-chip conversion
clock, an accurate reference, and a high speed serial interface.
The conversion process and data acquisition are controlled
using a CONVST signal and an internal oscillator. The AD7091R
has a serial interface allowing data to be read after the conversion, while achieving 1 MSPS throughput rate. The AD7091R
uses advanced design and process techniques to achieve
ultralow power dissipation at high throughput rates. An onchip, accurate 2.5 V reference is available.
Complete specifications for the AD7091R are provided in the
AD7091R data sheet, available from Analog Devices, which
should be consulted in conjunction with this user guide when
using the evaluation board.
Full details on the EVAL-SDP-CB1Z are available at
http://www.analog.com/EVAL-SDP-CB1Z.
The output from the supply is provided through a 2.0 mm inner
diameter jack that connects to the evaluation board at J1. The 9
V supply is connected to the on-board 5 V linear regulator that
supplies the correct bias to each of the various sections on the
board and the EVAL-SDP-CB1Z board.
When using this evaluation board with the EVAL-SDP-CB1Z
board, it is necessary to power the board through the J1
connector.
If the evaluation board is used without the 9 V adapter, an
external power supply in the range of 2.7 V to 5.25 V must be
connected to the VDD input to supply the AD7091R VDD pin. In
addition, an external supply in the range of 1.65 V to 5.25 V
must be connected to the VDRIVE input to supply the
AD7091R VDRIVE pin.
Each supply is decoupled on this board using 10 µF tantalum
and 100 nF multilayer ceramic capacitors.
There are two main ground planes, AGND and DGND. These
are connected at one location close to the AD7091R.
Caution
When the EVAL-AD7091RSDZ evaluation board is connected to
the EVAL-SDP-CB1Z, care must be taken to ensure that, if an
external voltage is supplied to the VDRIVE input connector, J3,
the voltage does not exceed 3.3 V. Otherwise, permanent
damage may occur to the EVAL-SDP-CB1Z board.
HARDWARE LINK OPTIONS
The functions of the link options are described in Table 2.
The default setup is configured to operate the board with
the mains power supply adapter and to interface to the
EVAL-SDP-CB1Z board.
Table 1. External Power Supplies Required
POWER SUPPLIES
Care should be taken before applying power and signals to
the evaluation board to ensure that all link positions are set
according to the required operating mode. See Table 2 for the
complete list of link options.

AD7091R User Guide
EVAL-AD7091RSDZ BASIC HARDWARE SETUP
The EVAL-AD7091RSDZ board connects to the EVAL-SDP-CB1Z
system demonstration platform board. The EVAL-SDP-CB1Z
board is the controller board, which is the communication link
between the PC and the main evaluation board. Figure 2 shows
a photograph of the connections between the EVAL-AD7091RSDZ
daughter board and the EVAL-SDP-CB1Z board.
The analog input range to the AD7091R is 0 V to VREF and
should not be exceeded. When using the on-chip reference, VREF
is 2.5 V. An input signal in the range of 2.5 V p-p should be
connected to the EVAL-AD7091RSDZ board via VIN or VINB.
A bipolar input signal should be connected to VINB, the J6
connector. This signal is biased to 1.25 V via the bias up
circuitry on the EVAL-AD7091RSDZ. The signal source should
be a low impedance source. An on-board unity gain amplifier
buffers the signal to the AD7091R. This is the default configuration on the EVAL-AD7091RSDZ.
A unipolar input signal should be connected to VIN, the J5
connector. An on-board unity gain amplifier buffers the signal
to the AD7091R.
Before connecting power, connect the EVAL-AD7091RSDZ
board to Connector A on the EVAL-SDP-CB1Z board. A nylon
screw/nut set is included in the EVAL-AD7091RSDZ kit and can
be used to ensure that the EVAL-AD7091RSDZ and EVAL-SDPCB1Z boards are connected firmly together.
Ensure that the link options are in the default positions as
outlined in Table 2.
After the EVAL-AD7091RSDZ board and the EVAL-SDP-CB1Z
board are connected securely, connect the power to the EVALAD7091RSDZ board. The EVAL-AD7091RSDZ board requires
an external power supply adapter, which is included in the
evaluation board kit. Connect this power supply to Connector
J1 on the EVAL-AD7091RSDZ board. For further details on the
required power supply connections and options, see the Power
Supplies section.
Before connecting the EVAL-SDP-CB1Z board to your PC,
ensure that the EVAL-AD7091RSDZ software has been installed
from the enclosed CD. The full software installation procedure
is detailed in the Evaluation Board Software section.
Finally, connect the EVAL-SDP-CB1Z board to the PC via the
USB cable enclosed in the EVAL-SDP-CB1Z kit. If using a
Windows XP platform, you may need to search for the EVALSDP-CB1Z drivers. Choose to automatically search for the
drivers for the EVAL-SDP-CB1Z board if prompted by the
operating system.

AC TESTING—FFT CAPTURE
Figure 17 shows the FFT capture tab. This 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. To perform an ac
test, apply a sinusoidal signal to the evaluation board at the
SMB input, J5 or J6. Low distortion, better than 115 dB, 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 consideration should be taken in the
choice. Furthermore, if using a low frequency band-pass filter
when the full-scale input range is more than a few volts peak
to peak, it is recommended to use the on-board amplifiers to
amplify the signal, thus preventing the filter from distorting the
input signal.
Figure 17 displays the results of the captured data.
