Abstract:
The A/D devices used in automatic weather stations and the authenticated devices are usually 12 bits or below, because the stability and accuracy of data conversion are determined by the bits of A/D devices, which cannot meet the needs of new meteorological equipment. Using the 24bit serial A/D device, AD7714, produced by Analog Devices Company, is used in the design of the new circuit s for the operational system. The functions and characteristics of AD7714, some of the source codes, and the AD7714based design methods of software and hardware are introduced. Besides, some technical problems encountered in practical application are discussed.
