I want to give resistor divider signal to micro-controller ADC using opamp buffer to provide low impedance to ADC channel.
Now there is two scenario.
In scenario-1 the voltage across divider (V_divider) is not half of input voltage and voltage across ADC (V_ADC) is not equal to divider voltage.
In scenario-2 , R3 is removed now.
Why does the V_divider is equal to V_Input and V_ADC is equal to V_divider.
Could anybody correct the simulation for actual results.
Thanks in Advance !!!!
