Gain formulae
Given a desired Gain the Gain resistor Rg can be calculated as follow.
Rg = 100000/(G -1)
G is the Amplification Gain.
Rg is the resistor value in ohm.
or deducing the gain from the resistor will be using
G = 100000/Rg + 1
ADC Full Scale
The RPICT7V1 Version 4 uses 4.096V voltage reference for the ADC. Signals are centred on 2.048V. Therefore the waveform can have a max amplitude of 2.048V. We will call this Vadc/2.
Vadc = 4.096V
