本文介绍的多路数据采集系统是以８０３１作为微处理器，以ＡＤ１６７４作为高精度的模数转换器。并采用ＡＤ７５０６作为多路开关以实现多路数据采集，并采用程控放大器，实现放大倍数的可程控性
This article describes the multi-channel data acquisition system is based on the 8031 as a microprocessor to AD1674 as a high-precision analog-to-digital converter. And use AD7506 as a multi-channel switch in order to achieve multi-channel data acquisition, and the use of programmable amplifiers, programmable to achieve magnification
