EVALUATION BOARD DESCRIPTION
The
EVAL-ADAS3022EDZ
is an evaluation board for the
ADAS3022
16-bit data acquisition system (DAS). This device
integrates an 8-channel multiplexer, a high impedance
programmable gain instrumentation amplifier (PGIA) stage with
a high common-mode rejection, a precision 16-bit successive
approximation (no latency) analog-to-digital converter and
precision 4.096 V reference offering an aggregate throughput
of 1 million samples per second (1 MSPS).
The evaluation board is designed to demonstrate the perform-
ance of the
ADAS3022
and to provide an easy-to-understand
interface for a variety of system applications. A full description
of this product is available in the data sheet and should be
consulted when utilizing this evaluation board.
The evaluation board is intended to be used with the Analog
Devices, Inc., converter evaluation and development (CED)
board,
EVAL-CED1Z
, a USB-based capture board connected
to P4, the 96-pin interface.
On-board components include a high precision, buffered band
gap 4.096 V reference (
ADR434
), reference buffers (
AD8032
),
passive signal conditioning circuitry, and an FPGA for deserializing
the serial conversion results and configuring the
ADAS3022
via
a 4-wire serial interface.
The P3 connector allows users to test their own interface with
or without the optional Altera FPGA, U6 (programmed using
the P2 and passive serial EEPROM, U5).
