 QUICK START GUIDE 

RECOMMENDED QUICK START GUIDE 

Follow these steps to set up the board: 
1.

 

Disconnect the 

SDP-B

 board from the USB port of the PC. 

Install the 

EVAL-AD7175-2SDZ

 software from the 

enclosed CD. Restart the PC after installation. 

2.

 

Connect the 

EVAL-SDP-CB1Z

 board to the  

EVAL-AD7175-2SDZ

 board, as shown in Figure 2. 

3.

 

Fasten the two boards with the enclosed plastic  
screw washer set. 

4.

 

Connect the external 9 V power supply to Connector J5 of 
the 

EVAL-AD7175-2SDZ

 board as shown in Figure 2. Set 

LK2 to Position B. 

5.

 

Connect the SDP board to the PC via the USB cable. For 
Windows® XP, you may need to search for the SDP drivers. 
Choose to automatically search for the drivers for the 

SDP-B

 

board if prompted by the operating system. 

6.

 

Launch the 

EVAL-AD7175-2SDZ

 software from the 

Analog Devices subfolder in the 

Programs

 menu. 

 

QUICK START NOISE TEST 

Use the following procedure to quickly test the noise 
performance: 
1.

 

Insert Link LK5 to Link LK9 to initiate the noise 
performance test mode. In this mode, analog input 
channels short to the REFOUT pin. 

2.

 

Click 

Start Sampling

 to acquire samples from the ADC 

(see Figure 7). 

The 

Samples 

numeric control in the top right corner of the 

main window sets the number of samples collected in each 
batch.
