EVALUATION BOARD PHOTOGRAPH
EVAL-ADAQ23875FMCZ
GENERAL DESCRIPTION
The EVAL-ADAQ23875FMCZ evaluation board enables
simplified evaluation of the
high speed, precision µModule® data acquisition solution.
The evaluation board demonstrates the performance of the
ADAQ23875
µModule and is a versatile tool for a variety of
applications.
The ADAQ23875 µModule combines multiple common signal
processing and conditioning blocks in a single device that includes
a low noise, fully differential analog-to-digital converter (ADC)
driver, a stable reference buffer, a high resolution, 16-bit, 15 MSPS
successive approximation register (SAR) ADC, and the critical
passive components necessary for optimum performance. A full
description of this product is available in the
sheet, which must be consulted when using the evaluation board.
The EVAL-ADAQ23875FMCZ evaluation board interfaces with
the high speed system demonstration platform,
SDP-CH1Z) via a 160-pin connector, as shown in Figure 2.
