ADC
The ADC data output is a 16bit data. The MODE[1:0] bits controls the tradeoff between the duration of the
counting phase and the resolution. Mode 00 is the fastest but also the least accurate mode whereas the
mode 11 is the most accurate but the slowest. The LOW_POWER bit allows the user to reduce the power
consumption of the ADC
(*): To get the sampling rate of the system, the initialization time must be added to the conversion time. This
time is programmable as it depends on the selected sensor (by default it is 150 µs).
-40° C < Temp < 105°C, unless otherwise specified.
