Hello All,
I am facing issues to interface a signal from capacitive divider to MCU ADC.
Why does signal goes negative once I connect with 1 Meg... and if i remove 1 Meg signal looks good.
My intention is if i connect this signal to MCU ADC it should not distort.
So could anybody guide me how to interface with MCU
MCU to be used for application is STM32F205
Please help me out .
Attached schematic for reference .
Thanks in Advance !!!
