GENERAL DESCRIPTION
The
EVAL-ADE7903EBZ
board, which along with the
allows users to evaluate the performance of the
ADC in a context very close to an actual single-phase meter
implementation. There is an isolated version of the
Σ-Δ ADC available, the ADE7913; to evaluate the isolated
Σ-Δ ADC, use the
ADE7913
from Analog Devices, Inc.). Evaluation software written in
LabVIEW® provides access to the registers of the
using a PC interface.
Full specifications on the
data sheet, which should be consulted in conjunction with this
user guide when using this evaluation board.
