(*) The internal temperature sensor requires a calibration. On the full range the calibration allows an accuracy
of ±2.5° C. This can be improved within a reduced temperature range (e.g. ±1° C within -30 and 30°C), or by
using a remote (external) temperature probe (+/-0.5° over the full range)

Conditions / Comment
Code PGA1gain[3:0] =
0000 (gain=8) -> 1010 (gain=75)
Code PGA2gain[2:0] =
000 (gain=1) -> 111 (gain=8)
(= offset max of the sensor)
8-bits DAC (7 bits + sign)
Ratio-metric, to cancel the offset of the
sensor
Gain (PGA) = 8
(if higher, PGA_Dir should be Vref/2
divided by the gain)
7 bits + 1 bit sign
