GENERAL DESCRIPTION
The
EVAL-AD7091SDZ
is a full-featured evaluation board
designed to allow the user to easily evaluate all features of the
AD7091
analog-to-digital converter. A 7 V to 9 V external
bench top supply is regulated to ±5 V and 3.3 V to supply the
AD7091
and support all necessary components. The
EVAL-
AD7091SDZ
board connects to the USB port of the PC by
connecting to the
EVAL-SDP-CB1Z
motherboard.
The
EVAL-AD7091SDZ
software provides dynamic perform-
ance analysis in the form of waveform graphs, histograms, and
FFT analysis for ADC performance evaluation.
On-board components include the
AD8031
high speed precision
rail-to-rail op amp, the
AD8032
high speed precision rail-to-rail
dual op amp, the
ADP3303
high accuracy 200 mA, low dropout,
linear regulator, and the
ADP7104
adjustable low noise 500 mA
low dropout linear regulator. Other on-board components include
the
ADG3308
bidirectional logic level translator, the
REF196
3.3 V
precision voltage reference, the
ADM1185
quad voltage monitor
and sequencer, and the
ADP1613
step-up dc-to-dc switching
converter.
