The EVAL-AD7190EBZ is an evaluation board for AD7190 4.8KHz ultralow noise 24bit sigma delta ADCs. The AD7190 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. The AD7190 evaluation kit is a powerful tool for exploring and evaluating the AD7190 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 AD7192 internal settings, and generally helps in understanding the part features and performance.
