<GAIN CORRECTION – CH B> +0.001 dB to +0.134 dB, in 128 steps
Using the FINE GAIN ADJUST register bits, the channel gain can be trimmed in fine steps. The trim is only
additive, has 128 steps & a range of 0.134dB. The relation between the FINE GAIN ADJUST bits & the trimmed
channel gain is:
Δ Channel Gain = 20 × log10[1 + (FINE GAIN ADJUST/8192)]
Note that the total device gain = ADC gain +
Δ Channel gain. The ADC gain is determined by register bits <GAIN
