Hello everyone.
I used ADS 1115 ADC to digitalize resultant signal of four LC parallel connected via excitation trim. However I have trouble precision with ADC and I don't know the cause. I used 0.1875mV/bit resolution and measured AD620's output. The measurement is 65mV but I saw measurement using Arduino's serial monitor and output value is around 0.228 V. People on foros said ADS 1115 isn't the best option to digitalize LC's signals and purposed other option as ADS1231/2.
I hope anyone give me any answer for my problem.
Regards.
Meca.
