摘要
ADuC812是AD公司研制的高性能 8位单片机 ,内置有看门狗和定时器电路 ,它在单个芯片内包含了高性能的自校准多通道 12位ADC ,2个 12位DAC ,转换速度可达 5 μs。文章论述了用ADuC812实现供热系统中控制器的软硬件设计 ,并介绍了为提高AD/DA精度所采取的措施。
ADuC812 is a high performance 8 bit singlechip developed by AD Inc.with watchdog and timer circuits inside.It incorporates a high performance self calibrating multi-channel 12 bit ADC, dual 12 bit DACs on a single chip,and its conversion speed can be as hign as 5us.The software and hardware design of the controller in the heat supply system which based on ADuC812,is introduced,and some steps to improve the precisions of AD/DA are presented.
