16 bit ADC Module resolution (ADS1115)
GrégoryMignot 2022-07-05 10:37:55 647 Views1 Replies Hi,
I bought a 16 bits adc module recently, and I see that the values are in millivolts (in int16_t in the library from 0 to 6143).
How to get the 16 bits resolution (a resolution of 0.0078125mV) ? and not only 1mV whatever the measurement range (even in eGAIN_SIXTEEN) ?
unless I didn't understand something...
This is quite urgent,
Thanks in advance.

According to the datasheet of Gravity: I2C ADS1115 16-Bit ADC Module, due to the restriction of chips, the resolution is 0.1875mv.
You can change the resolution by function in our library.
