EVALUATION BOARD DESCRIPTION
The EVAL-AD7276SDZ is a full-featured evaluation board,
designed to allow the user to easily evaluate all features of the
AD7276. The evaluation board can be controlled via the system
demonstration platform (SDP) connector (J8). The EVAL-SDP-
CB1Z board allows the evaluation board to be controlled via the
USB port of a PC using the AD7276 evaluation software.
The EVAL-AD7276SDZ generates all required power supplies
on board and supplies power to the EVAL-SDP-CB1Z controller
board.
On-board components include the:
•
AD8022: Dual High Speed, Low Noise Op Amp
•
ADA4000-1: Single, Low Cost, Precision JFET Input
Operational Amplifier
