为什么STM32F429IGT6有的OPTCR是0x0FFFAAED,有的是0x4FFFAAFD。 0x4FFFAAFD的这个怎么重新配置成0x0FFFAAED?

我是用ADS7254进行数据采集时,可以正常采集正电压,采集负电压时数值接几乎0。我查阅数据手册后似乎未找到与器件测量极性相关的设置,可能会是哪里出了问题呢?

ADS127L01datasheet的8.5.8节的菊花链操作章节,在figure8-36进行了菊花链连接举例。如下图 菊花链模式下,必须将引脚SDO/DRDY配置成“output-only”模式,我打算还是采用硬件的方式捕获“转换数据准备好”的信号,那么请问在菊花链模式下,引脚PIN14_DRDY从哪个ADC中引出来?是从最后一个“ADS127L11(4)”引出DRDY吗?

现在项目设计,需要用到8路输出的DAC,每一路都可以配置成10KHZ的脉冲波输出(0-2.5V),dac128s085是3V供电,2.5V参考电压,请问这个DAC可以用吗?如何计算DAC的输出带宽,从那些参数可以看出?如果能提供计算方法,那就更好了,谢谢!

1. 为什么ADS114S08的Input-referred noise不随Date Rate变化,而ADS124S08的会随Date Rate变化?而且对于ADS114S08低分辨率的ADC,量化噪声占主导地位,不应该更易受Date Rate影响吗? 2. 为什么ADS114S08的Input-referred noise恰好为1LSB?
