I am using an ADS1115 as an analog to digital converter.
R2 and C2 are used as a low pass filter. I have used two schottky diodes as voltage clippers to protect against over voltage. To avoid floating condition I have put a pull down resistor of 10K(R6.) I have modelled a resistive voltage sensor as a voltage divider. I have used a 100K resistor to model the input impedance of the ADC .
The issue is because of the pull down resistor I am getting wrong analog voltage readings.
Any suggestions for modifications in circuit so that I can read proper analog values?
