2) _{tupd = 8192 / (25 x fCLK) for FIR_BYP = 0}
t_upd = 8192 / (100 x f_CLK) for FIR_BYP = 1
3) _{tsettle = 2 x tupd , after change of ADC input source}
4) _{Output values are valid up to this limit. Above it, corrupted results may occur due to non-linearity of the ADC.}
5) _{The internal quantization is typically 5.166 µV per digit.}
6) _{Correspond to max. GMR output value.}
