Hello Everyone,
I am facing an issue with ADS1115 ADC which is 16 bit ADC. I am able to communicate mircocontroller and ADC. I am even able to get the ADC counts. Though counts are fluctuating I have used averaging method to get proper counts.
The PGA is +/- 2.048. I am using channel 0. I am getting below results,
mV ADC count
200 200
300 300
1000 1000
1024 1024
1058 1058
To convert ADC count into voltage I am dividing ADC count by 1000. My question is how to get fourth digit after decimal point.
Suppose mV=1058.5 I need converted value should be 0.10585.
As the ADC is 16 bit, can anyone please explain me how to get fourth digit after the decimal point.
