ADC Converter
The ME910G1 is includes one AD converter. It can read a voltage level in the range of
0÷1.8 volts applied on the ADC pin input, store it and convert it into 10 bit word.
The input line is named as ADC_IN1 and it is available on Pad B1
The following table is showing the ADC characteristics:
Item Min Typical Max Unit
Input Voltage range 0 - 1.8 Volt
AD conversion - - 10 bits
Input Resistance 1 - - Mohm
Input Capacitance - 1 - pF
Table 26: ADC characteristics
The ADC could be controlled using an AT command.
The command is
AT#ADC=1,2
The read value is expressed in mV
