Precision autonomous modular 24-bits geophysical data acquisition system

The article is devoted to the details of the development of a new small-size modular low-power data acquisition system based on a 24-bit analog-to-digital converter chip. Modern geophysical observations are now impossible to imagine without using a wide variety of electronic systems for collecting information. Any parameter or phenomenon what we would like to register or measure everywhere will have the obligatory element - an analog-to-digital converter. However, unfortunately, it is often impossible to find an ideal system for solving any necessary task. In geophysical research, many tasks turn out to be a "piece goods" for which it is necessary to have its own data acquisition system, which has its own specific characteristics. This is one of the reasons for the development of all new versions of data acquisition systems up to the present. The article describes the development of such a specialized small-size modular data acquisition system. It is given the description of its main functional blocks; special attention is paying to the most important parameters that affect both the quality of the entire system as a whole and the improvement of the effective number of bits by minimizing the level of internal system self-noise.
