GENERAL DESCRIPTION
The EVAL-ADAQ23876FMCZ and EVAL-ADAQ23878FMCZ eval-
uation boards (see
Figure
the ADAQ23876 and ADAQ23878 15 MSPS, 16-/18-bit, high
speed, precision µModule
The EVAL-ADAQ23876FMCZ and EVAL-ADAQ23878FMCZ dem-
onstrate the performance of the ADAQ23876 and ADAQ23878
µModules, respectively, and are versatile tools for a variety of
applications.
The ADAQ23876 and ADAQ23878 µModules combine multiple
common signal processing and conditioning blocks into devices
that include a low noise, fully differential analog-to-digital converter
(ADC) driver, a stable reference buffer, high resolution, 16-/18-bit,
15 MSPS successive approximation register (SAR) ADCs, and the
critical passive components necessary for optimum performance.
The EVAL-ADAQ23876FMCZ and EVAL-ADAQ23878FMCZ inter-
face with a high speed system demonstration platform (SDP),
SDP-H1 (EVAL-SDP-CH1Z), via a 160-pin connector, as shown in
Figure
2.
For full details on the ADAQ23876 and ADAQ23878, see the
ADAQ23876 and ADAQ23878 data sheets, which must be con-
sulted in conjunction with this user guide when using the EVAL-
ADAQ23876FMCZ or EVAL-ADAQ23878FMCZ.
