Hi,
The board could hit input current limit. Could you try below register settings with input current limit/protection disabled?

问题可能出现在输入端的R4, 提高了输入的共模电压，您可以参见手册的Figure 9-2.Input Common-Mode Voltage vs Output Voltage at G = 1 V/V了解输入共模电压与输出电压范围的关系，也可以通过 input and output range design calculator 工具得出具体的输入电压范围。

Hi,
Thanks for the feedback! Input levels in dBm are relative. It would be helpful to have the full signal range to the ADC input in volts. For now, I will assume it is peak-to-peak 0.5V to 12V = 12V-0.5V = 11.5Vpp, as you mentioned in your first post.…
I do not see anything with the schematic or board layout that would explain the readings exceeding full scale.
However, sometimes customers do not convert the raw ADC code with the correct sign bit. When the input is slightly negative (can be caused by…
Part Number: MSP430AFE253
Many documents mention that using a SD ADC requires adding an anti-aliasing RC circuit as its front-end for differential inputs, as shown in the first figure below. Actual tests on the MSP430AFE's SD24_A achieved a sampling ripple…
您好
MATLAB ADC block will allow users to take input through the ADC channel 14 in this case and will give an output on ADCRESULT14 register because of the selected SOC.
I am unable to understand the question here. Can you please specify what numerical…
