GENERAL DESCRIPTION

The
EVAL-AD7403FMCZ
designed to allow the user to easily evaluate all features of the
AD7403
isolated analog-to-digital converter (ADC). The
evaluation board can be controlled by the
the FMCZ connector (J9). The SDP-H1 board
CH1Z) allows the evaluation board to be controlled through a
USB port of a PC using the evaluation board software, which is
available for download from the
page or from the installer CD included in the evaluation board kit.
On-board components include the following:
ADuM6000: isolated iCoupler® 5 kV, dc-to-dc converter
ADP2441: 36 V, 1 A, synchronous, step-down dc-to-dc regulator
ADP7104ARDZ-5.0: 5 V low noise LDO
