SWRS224A – FEBRUARY 2019 – REVISED AUGUST 2019
NOTE
The ADC inputs are tolerant up to 1.8 V (see
for further details on the useable range of the ADC). The digital pads can tolerate
up to 3.6 V. Hence, take care to prevent accidental damage to the ADC inputs. TI recommends first disabling the output buffers of the digital I/Os
corresponding to the desired ADC channel (that is, converted to Hi-Z state), and thereafter disabling the respective pass switches (S7 [Pin 47],
S8 [Pin 48], S9 [Pin 49], and S10 [Pin 50]). For more information, see
