This user guide describes the evaluation board for the AD7190/ 
AD7192, which are 4.8 kHz ultralow noise 24-bit sigma-delta 
(Σ-Δ) ADCs. The AD7190/AD7192 are complete analog front 
ends for low frequency measurement applications. The parts 
contain two differential inputs/four pseudo differential inputs, 
and include a low noise instrumentation amplifier, reference 
detect, and a low-side power switch.  

Full data on the AD7190/AD7192 is available in the 

and 

 data sheets available from Analog Devices, Inc., 

and should be consulted in conjunction with this user guide 
when using the evaluation board. 

The AD7190/AD7192 evaluation kit is a powerful tool for 
exploring and evaluating the AD7190/AD7192 features.  

The evaluation board can be operated in complete standalone, 
battery-powered mode. The LCD display is used to display the 
conversion data. 

When the board is connected to (and possibly powered from) a 
PC via a standard USB interface, the PC software allows the 
graphical display of real-time data, logs them into a text file, 
allows you to modify the AD7190/AD7192 internal settings, 
and generally helps in understanding the part features and 
performance. 

Finally, the board’s flexible interface structure allows it to be 
connected in a number of useful configurations. For example, 
the digital section of the evaluation board can be used inde-
pendently as a convenient digital interface for a user’s own 
sensor design PCB or module containing the AD7190/AD7192. 
Alternatively, an external microcontroller can be interfaced to 
the AD7190/AD7192 and thus the evaluation board can act as a 
complete analog front end for creating and debugging software 
on the user’s own digital platform.
