Evaluation Board for the 

ADA2200

 Synchronous Demodulator 

 

EVALUATION BOARD FEATURES 

Easy to use evaluation board 
Simple, in-phase (I) and quadrature (Q) demodulation in a 

single channel 

Differential or single-ended input/output 
USB powered 
On-board oscillator 
EEPROM programmable option 
Synchronization signals available for external devices 

GENERAL DESCRIPTION 

This user guide describes the evaluation board that contains the 
Analog Devices, Inc., 

ADA2200

 sampled analog, synchronous 

demodulator. The circuit configurations available through the 

ADA2200-EVALZ

 enable the user to exercise its full set of features.  

The 

ADA2200-EVALZ

 simplifies signal connections to standard 

test equipment. Inputs, outputs, supplies, and other circuit test 

points can be easily accessed via test clips, differential probes, or 
standard SMA cables. In addition, the board can be easily powered 
from any USB port through the included USB cable.  
The 

ADA2200-EVALZ

 performs amplitude and phase 

measurements on the signals applied to its inputs. The selection 
between I and Q components is accomplished with a simple 
toggle switch. 
The recommended configuration for initial evaluation is shown 
in Figure 2. See the Quick Start and Setup Procedure section for 
more details. 
Complete specifications for th

ADA2200

 are available in the 

ADA2200

 data sheet, which must be consulted in conjunction with 

this user guide when using the evaluation board. The data sheet 
and user guide are available to download from th

ADA2200
