GENERAL DESCRIPTION 

The 

EVAL-ADE7903EBZ

 evaluation kit includes the evaluation 

board, which along with the 

EVAL-SDP-CB1Z

 SDP-B board, 

allows users to evaluate the performance of the 

ADE7903

 Σ-Δ 

ADC in a context very close to an actual single-phase meter 
implementation. There is an isolated version of the 

ADE7903

  

Σ-Δ ADC available, the 

ADE7913

; to evaluate the isolated  

Σ-Δ ADC, use the 

ADE7913

 evaluation kit (order separately 

from Analog Devices, Inc.). Evaluation software written in 
LabVIEW® provides access to the registers of the 

ADE7903

 

using a PC interface.  
Full specifications on the 

ADE7903

 are available in the product 

data sheet, which should be consulted in conjunction with this 
user guide when using this evaluation board.
