| 摘 要： | 研究了一种基于数字电位器MAX5160的直流电压信号系统。通过按键输入期望的直流电压值,然后由微处理器ARM1138根据该数值对数字电位器进行控制,可以得到多级直流电压信号,并使该系统的最大误差为0.02V、电压信号范围为0～4.98V且精度为±0.0112V。实验表明：所设计的直流电压信号系统具有灵活、方便、可靠测试的特点,并可输出多级直流电压信号。

| Abstract: | A DC voltage signal system based on digital potentiometer MAX5160 is investigated.By the means of inputting the value of the expected DC voltage via the keys and controlling the digital potentiometer via microprocessor ARM1138,the multi-level DC voltage signal can be obtained.The maximum error of 0.02 V,the voltage signal scale of 0～4.98 V and the precision of ±0.0112 V are obtained.The experiment results show that the signal system with the characteristics of flexible,convenient and reliable test can output the multi-level DC voltage signal. |
