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 V

REF

 and 

should not be exceeded. When using the on-chip reference, V

REF

 

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 configura-

tion 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-SDP-

CB1Z

 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 

EVAL-

AD7091RSDZ

 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 

EVAL-

SDP-CB1Z

 drivers. Choose to automatically search for the 

drivers for the 

EVAL-SDP-CB1Z

 board if prompted by the 

operating system.
