MLX90320
Automotive small sensor interface
external temperature sensor. If TMP_GAIN[2:0] = 111,
the gain is the highest. If TMP_GAIN[2:0] = 000, the
gain is the lowest. The gain is calibrated in that way that
the temperature sensor output is within the ADC range.
The internal temperature sensor gain calibration is only
factory set.
