GENERAL DESCRIPTION

The EVAL-AD7366SDZ/EVAL-AD7367SDZ is a full-featured
evaluation board, designed to allow the user to easily evaluate
all features of the AD7366/AD7367. The evaluation board
can be control-led via the system demonstration platform
(SDP) connector (J8). The
EVAL-SDP-CB1Z
the evaluation board to be controlled via the USB port of a
PC using the
AD7366/AD7367
The EVAL-AD7366SDZ/EVAL-AD7367SDZ generates all
required power supplies on board and supplies power to the
EVAL-SDP-CB1Z
controller board.
On-board components include
•
AD8021: Low noise, high speed amplifier for 16-bit
systems
•
ADP1613: Step-up PWM dc-to-dc switching converter
•
ADP3303-5: High accuracy anyCAP™ 200 mA low dropout
linear regulator
•
ADP2301: 1.2 A 20 V, 1.4 MHz nonsynchronous step-
down switching regulator
•
ADP1720: 50 mA, high voltage, micropower linear
regulator
•
ADM1185: Quad voltage monitor and sequencer
•
ADG3308: Low voltage, 1.15 V to 5.5 V, 8-channel
bidirectional logic level translator
•
AD780: 5 V/3.0 V ultrahigh precision band gap voltage
