9.5. ADC Converter
9.5.1. Description
The LE910Cx module provides three 8-bit Analog to Digital converters. Each ADC reads the
voltage level applied on the relevant pin, converts it, and stores it into an 8-bit word.
Table 35 shows the ADC characteristics.

9.5.2. Using the ADC Converter
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 LE9x0 AT Command User Guide 0 for the full description of this function.
9.6. Using the Temperature Monitor Function
The Temperature Monitor permits to control the module’s internal temperature and, if properly
set (see the #TEMPMON command in LE9x0 AT Command User Guide), raises a GPIO to High Logic
level when the maximum temperature is reached.
