摘要
使用通常的单片机、A/D转换器等芯片构造一个数据采集系统 ,往往设计周期长 ,成本较高。ADμC812芯片内部集成了 12位多路A/D转换器和D/A输出 ,能灵活对芯片进行编程 ,大大降低了数据采集系统的开发时间和成本。ADμC812芯片内部装有工厂编程的校准系数 ,它在上电时自动下载到ADC ,可以获得很高的精度 ,并且可以采用软件进一步校准 ,从而获得更高的精度 。
The period to design a data acquisition system using traditional MCU and A/D converter is always long and its expense is always high. a 12-bit multichannel ADC and two 12-bit DACs is integrated in the ADμC812,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 downloaded on any power-on-reset event to initialize the ADC calibration registers.
