Industrial Automatic Control Systems and Controllers Annotation << Back 24-bit Analog to Digital Converter into the Field Microcontroller Apparatus for Seismic Exploration L.N. Senin, T.E. Senina, M.N. Voskresensky The circuits by sigma-delta modulators different orders have wide expansion today. Potentialities increase number of integrators is a great merit. This is increase sensitivity and dynamic range of analog to digital conversion. In the article given description 24-bit analog to digital converter with use integral sigma-delta modulator by fourth order. 8-bit AVR controller of common destination is control by this circuit. The equipment can be use as ADC by fi eld seismic apparatus or another geophysical devices. Keywords: analog to digital converter; sigma-delta modulator; controller of common destination; seismic apparatus. Contacts: E-mail: selenik@rambler.ru, E-mail: voskresenskiy-mn@mail.ru Pp. 58-63.
