adc电压计算 Vread =(Adc(readx)/4096(根据ADC位数不同,此处值不同))* Vref。读取通道17,因为是个定值,所以可以计算出Vref = 1.2*4096/Adc(read17)); 任意通道的电压值 Vread = (Adc(readx)/4096)*(1.2*4096/adc(read17))) = 1.2*Adc(readx)/Adc(read17) 其中参照电压=1.20V 选用外部参考基准电...
The bug extends to the automatically-calculate "Sample time" that is shown in the GUI, right below the "Sample time mode" dropdown box; this value is calculated using the wrong value 69 instead of 67.5.Also, the bug extends to the comments in fsl_lpadc.h: typedef enum _...
PURPOSE: A dual channel analog to digital converter (ADC) is provided to sample an input signal by using a sampling clock of each channel by solving a mismatching problem. CONSTITUTION: An ADC comprises an SHA (110), an MDAC (120-130), an SHA sampling clock generator, and a flash ADC ...
18.2.1, wherein a large number of time-interleaved photonic sampling channels each feed a 4b, 1GS/s CMOS ADC. The elec- trical input is sampled onto a hold capacitor using low-tempera- ture-grown (LT) GaAs photoconductive switches that are optical- ly triggered by a mode-locked laser ...
