Analog DevicesEVAL-AD7689EDZデータ変換開発ボードとキット

The EVAL-AD76MUXCBZ is an evaluation board for the 20
lead PulSAR AD7682, AD7689, AD7699, and AD7949 14-bit
and 16-bit PulSAR analog to digital converter (ADC) family.
These low power, successive approximation register (SAR)
architect-ture ADCs (see Ordering Guide for product list) offer
very high performance with up to 500kSPS throughput rate and
4 – 8 channels. The evaluation board is designed to demonstrate
the ADC's performance and to provide an easy to understand
interface for a variety of system applications. A full description
of the AD7682, AD7689, AD7699,The evaluation board can be operated as a stand alone or can be
used in conjunction with the Analog Devices EVAL-CED1Z
CED) USB based data capture board. Since the ADC’s being
evaluated are serial interface only, the EVAL-AD76MUXCBZ
contains the necessary logic to perform serial to parallel
conversion for this interface using the on board FPGA.
On-board components include a high precision band gap
reference, (ADR435), reference buffers, 8-signal conditioning
circuits with an op amp and an FGPA for digital logic. Also
included are separate low drop out regulators for supplying
special voltages of 1.2V and 7V which are not available from the
EVAL-CED1Z.
The board interfaces to the EVAL-CED1Z with a 96-pin DIN
connector. J1, J2 SMB connectors are provided for the low noise
analog signal source for CH0 and CH1 with the remaining channels (and CH0/1) available on an IDC connector, P1. J3 can
be used for providing an external common (COM) or
configured for any input channel.
