The on board ADC is 12-bit converter. It is able to read a voltage level in the range of 0 ~ 1.2 volts 
applied on the ADC pin input and store and convert it into 12 bit word.

The CE910 provides one Analog to Digital Converter.  

The input line is named as ADC_IN1 and it is available on pad B1. 

 

 

An AT command is available to use the ADC function.  

The command is AT#ADC=1,2.  The read value is expressed in mV 

Refer to SW User Guide or AT Commands Reference Guide for the full description of this function.
