14.2. ADC Converter
14.2.1. Description
The UL865-N3G V2 is provided by two A/D converters. They are 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 signal is available on the following pads:
PAD Name I/O Description Notes
13
ADC_IN1 AI
Analog/Digital converter
input
Accepted values 0 to 1.2V DC
14
ADC_IN2 AI
Analog/Digital converter
input
Accepted values 0 to 1.2V DC
14.2.2. 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.
