1.2.3.1.3 Analog input specification
Attention
The single-ended analog input has an extended range of 104.7% (e.g. 0xFFF correspond to +5.235V).
The differential analog input has an extended range of 121.8% (e.g. 0xFFF correspond to Vdiff = +6.09V).
1.2.3.1.3.1 Differential
Symbol Min. typical Max. Description Impact
V -5V +5V The input voltage between the
positive and negative input
pins.
Any voltage out of this range causes
saturation to the min/max ADC value.
V -1V +2.5V +5V The common mode voltage. Any voltage out of this range causes
saturation and inaccuracy in the
measurements.
V -15V +15V The tolerable voltage between
the positive input pin and
GND.
Any voltage out of this range damages
the analog input’s circuitry.
V -15V +15V The tolerable voltage between
the negative input pin and
GND.
Any voltage out of this range damages
the analog input’s circuitry.
R 13.6kΩ Internal input resistance
Error -1% +1% The input voltage between the
positive and negative input
pins.
