Gain Calibration PGA Gain 1. ADC gain correction for voltage input channels.
Stored as a signed number. Bit 14 is the sign bit and Bits[13:0] represent the
fractional part.
2 (maximum positive gain adjustment).
1.000061 (minimum positive gain adjustment).
1.0. ADC result multiplied by 1. No gain adjustment. Default value.
0.999939 (minimum negative gain adjustment).
0.5. ADC result multiplied by 0.5.
0.000061 (maximum negative gain adjustment).
0. Invalid value. Results in ADC result of 0.
