A software solution method of improving the data acquisition's accuracy of microconverter ADμC812

The period to design a data acquisition system using traditional MCU and A/D converter is always long and its expense is always high. ADμC812 microconverter adopts flash/electrically-erasable memory and high-performance analog measurement technique ,so it is easy to be programmed and used in data acquisition system,and the developing time and expense could be decreased sharply.The factory calibration results are stored in Flash memory and are automatically on any power-on-reset event to initialize the ADC calibration registers.
