I'm trying to read the output voltages of some LMC6001 op-amps through an ADS1115 ADC, to get higher resolution.
In the process of doing so, I'm reading huge fluctuations on the serial monitor without giving any input to the op-amp.
How do I reduce these fluctuations, so as to get stable ADC output values?
I tried to measure the offset voltage of just the op-amp at the output which is 0.3mV, but at the serial monitor the readings are varying from 5mV to 20mV.
Please help me to overcome this problem.
