INTRODUCTION
This user guide describes the EVAL-AD7193EBZ evaluation
board. The AD7193 is a 4.8 kHz, ultralow noise, 24-bit Σ-Δ ADC.
The AD7193 is a complete analog front end for low frequency
measurement applications. It contains four differential inputs/
8 pseudo differential inputs and includes a low noise instrumentation
amplifier, reference detect, and a low side power switch.
Full data on the AD7193 is available in the AD7193 data sheet
available from Analog Devices, Inc., and should be consulted in
conjunction with this user guide when using the evaluation board.
GENERAL DESCRIPTION
The AD7193 evaluation kit is a powerful tool for exploring and
evaluating the AD7193 features.
When the board is connected to (and possibly powered from) a
PC via a standard USB interface, the PC software allows for
• The graphical display of real-time data and logs this data
into a text file.
• The modification of the internal settings of the AD7193.
This software also helps in understanding the part features and
performance.
Finally, the flexible interface structure of the board allows it to
be connected in a number of useful configurations. For example,
the digital section of the evaluation board can be used
independently as a convenient digital interface for a user’s own
sensor design printed circuit board (PCB) or module containing
the AD7193. Alternatively, an external microcontroller can be
interfaced to the AD7193, and the evaluation board can act as a
complete analog front end for creating and debugging software
on the digital platform of the user.
