13.56MHZ SENSOR TAG / DATALOGGER IC
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).
