| Abstract: | The multi-channel data acquisition system by discrete elements has great shortages.Aimed at this question,the multi-channel data acquisition system composed by the IC of the low power data acquisition system ADS7870 of TI is proposed.The main characteristics of the ADS7870 and its operation principle,the interface circuits and part of program block diagram of the ADS7870 and the microcontroller MC68HC11 are given.This system can evidently raise the speed of the multiple data acquisition and the precision of the data conversion to reduce the power. |
