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；

The present invention provides an analog-to-digital converter (ADC) applied with a reference voltage scaling method. According to an embodiment of the present invention, the ADC includes: a first sub-ADC generating digital data by receiving voltage of a first range and comparing the voltage of ...
When VDDA_ADC, the internal reference is used, what's the high accuracy? For example if REF3233 0.01% is connected to the VDDA_ADC, can the accuracy still be 0.01% considering its also powering the ADC module ? I'm not sure whether the accuracy will be affect or not. ...
I am trying to implement the external reference of ADC by calling functionAUXADCEnableSync. And in the comments, I quote " //! When using external reference voltage, the AUX I/O 7 pin must have been //! configured in advance. This must be done manually when...

Hi, I am using a Tiny Gecko (EFM32TG11B140) to sample analog data and stream it out I2C as a slave device. I am using OPAMP2 to amplify the signal before feeding it into ADC0. I am running into an issue where the value measured by the ADC is c

内部基准电压，外部采样电压与之比较得出电压值
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...
