2.1.6. ADC Voltage Reference Each ADC block in Intel® MAX® 10 devices can independently use an internal or external voltage reference. In dual ADC devices, you can assign an internal voltage reference to one ADC block and an external voltage reference to the other ADC block. There is...
这个大概是因为音频信号在做线路传输时，按线路传输技术指标要求就是传输电压最大值为 1V；如DVD、VCD、功放、调音台、电视机等等都有线路输出、线路输入端。这些输出端、输入端都要求除了满足幅频特性外，就是要满足最大传输信号电压最大幅值为1V；
VIN×ADC输入阻抗/(ADC输入阻抗+外部电阻) 3.Reference Input Voltage参考电压在ADC数模转换的过程扮演着桥梁的作用,为ADC的输入模拟电压提供一个恒定参考。如下图是ADS8688的FSR(Full-scale input range),输入模拟量以参考电压为基准确定。 ADC在系统设计合理的情况下其全温度范围内的精度主要受参考电压的影响。ADS8...
https://community.nxp.com/t5/i-MX-RT/RT1170-ADC-Input-Voltage/m-p/1479993 1. Is my understanding correct about the internal block of CSCALE as shown in the following diagram?If the condition is NVCC_GPIO = 3.3V, VREFH = 1.8V and CSCALE = 1b, the ADC input range is 0 to 1.8V...

/* Enable ADC 1.2V channel_15 voltage reference */ ADC1->ADCFG |= ADC_ADCFG_VSEN; ADC_Cmd(ADC1, ENABLE); /* Enable ADC */ } 4 以MM32F0163D7P为例,读取出厂VDDA为3V3时采样1.2V电压的采样校准值,并换算成电压值,代码如下所示。
appears that ADCs have lost some internal voltage reference for conversion or have feedback faults in some mesh that compensates for the device's internal temperature and LaunchPad does not provide the pins for VREFHI and VREFLO to be externally adjusted. ...
