14.8 ADC Converter
14.8.1 Description
The HE910 is provided by one AD converter. It is able to read a voltage level in the range of
0÷1.2 volts applied on the ADC pin input, store and convert it into 10 bit word.
The following table is showing the ADC characteristics:
Min Typical Max Units
Input Voltage range 0 - 1.2 Volt
AD conversion - - 10 bits
Input Resistance 1 - - Mohm
Input Capacitance - 1 - pF
The input line is named as ADC_IN1 and it is available on Pad B1
14.8.2 Using 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 SW User Guide or AT Commands Reference Guide for the full description of this
function.
