Using a common microcontroller, ADC and other chips to construct a data acquisition system, the design cycle is often long, the cost is higher. The ADuC81 2 incorporates high-performance flash / electrically erasable memory technology and analog measurement technology for flexible programming of the chip, dramatically reducing the development time and cost of data acquisition systems. The ADuC81 2 features factory-programmed calibration coefficients that are automatically downloaded to the ADC at power-up for high accuracy and further software calibration for higher accuracy and maximum ADC performance
