GENERAL DESCRIPTION
The EV-ADAQ7767-1FMC1Z evaluation kit enables simple evalu-
ation of the ADAQ7767-1, flexible resistive input, anti-alias, 24-
®
bit, 1 MSPS, µModule
data acquisition (DAQ) solution. The EV-
ADAQ7767-1FMC1Z is used alongside a downloadable evaluation
software to fully configure the features of the ADAQ7767-1 and
display the conversion results in the time and frequency domains.
The EV-ADAQ7767-1FMC1Z connects to the USB port of a PC via
the SDP-H1 system demonstration platform board. By default, the
3.3 V rail is supplied by the SDP-H1 and regulated by the on-board
power solution to ±15 V and +5.3 V to power the ADAQ7767-1
and its support components. An integrated electronic piezoelectric
(IEPE)-interface and a pair of input buffers are included to evaluate
the ADAQ7767-1 across a variety of input types.
For a full description of the ADAQ7767-1, see the ADAQ7767-1
data sheet, which must be consulted in conjunction with this user
guide when using the EV-ADAQ7767-1FMC1Z evaluation board.
For the current schematic, layouts, and bill of materials, see the
EVAL-ADAQ7767-1
product page.
