x = P or T, notes 2 and 3
Note 1. Current consumption values are from forced mode at measurement rate 1Hz.
Note 2. GAINx=1 (x=P or T) setting bypasses the AFE amplifier and connects input signal directly to the ADC input.
Note 3. ADC resolution in bits is calculated as follows: VN_[bit] = log(1400mV / VN)/log(2) when VN is the RMS noise voltage at the input.
