GENERAL DESCRIPTION

The
AD4000/AD4001/AD4002/AD4003/AD4020
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/

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.
The
AD4002FMCZ/EVAL-AD4003FMCZ/EVAL-AD4020FMCZ
evaluation boards (see Figure 1) are ideal for use with the Analog
Devices, Inc., high speed system demonstration platform
evaluation board
(EVAL-SDP-CH1Z). These evaluation boards interface to the
SDP-H1
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.
