GENERAL DESCRIPTION
The
AD4000
/
AD4001
/
AD4002
/
AD4003
/
AD4020
family
evaluation board covers the ease of use, 16-/18-/20-bit,
precision successive approximation register (SAR) analog-to-
digital converters (ADCs). The
AD4000
/
AD4001
/
AD4002
/
AD4003
/
AD4020
are low power, 16-bit/18-bit/20-bit, precision
SAR ADCs that offer very high performance with throughputs
up to 2 MSPS (1.8 MSPS for the
AD4020
). The evaluation board is
designed to demonstrate the performance of the
AD4000
/
AD4001
/
AD4002
/
AD4003
/
AD4020
family of ADCs and to provide an
easy to understand interface for a variety of system applications.
A full description of these products is available in their
respective data sheets, which must be consulted when using this
evaluation board.

evaluation boards (see Figure 1) are ideal for use with the Analog
Devices, Inc., high speed system demonstration platform
(
EVAL-SDP-CH1Z
). These evaluation boards interface to the
SDP-H1
board via a 120-pin connector. SMA connectors, JP2
and JP3, are provided for the low noise analog signal source.
On-board components include a high precision buffered band gap
5.0 V reference (the
ADR4550
), a reference buffer (the
ADA4807-1
),
a common-mode buffer (the
ADA4807-1
), a signal conditioning
circuit with two op amps (the
ADA4807-1
), and a power supply to
derive the necessary voltage levels to supply all voltage needs.
The
EVAL-AD4000FMCZ
,
EVAL-AD4001FMCZ
,
EVAL-
AD4002FMCZ
, and
EVAL-AD4003FMCZ
are populated with
the
AD4000
,
AD4001
,
AD4002
, and
AD4003
, respectively.
However, these boards can be used to evaluate the performance
of the
AD4004
,
AD4005
,
AD4006
,
AD4007
,
AD4008
,
AD4010
,
and
AD4011
by limiting the sample rate in the evaluation
software to the maximum sample rate of the specific ADC.
For example, the
AD4000
on the
EVAL-AD4000FMCZ
can be
used to evaluate the performance of the
AD4004
if the sample
rate is limited to 1 MSPS. See the data sheet of each product for
its corresponding evaluation board.
