GENERAL DESCRIPTION 

This user guide describes the evaluation board for the 

AD8209A

a high voltage, single-supply, precision difference 

amplifier. The design of this board emphasizes simplicity and 
ease of use; the board can be readily mounted with a current 
sense resistor of a maximum standard size of 2818. The board 
design also allows flexibility with loads. This board comes with 
vector pins for the input and output terminals in a predefined 
configuration. 

The 

AD8209A

 data sheet covers the details of the device 

operation and describes the basic connections for operating the 
device, as well as common circuit configurations and applications. 
Consult the data sheet in conjunction with this user guide for a 
better understanding of the device operation, especially when 
powering up the evaluation board for the first time.
