SIM5320AL_User Manual_V1.01 2014-08-20
User can introduce a signal in the ADC pin directly and use the AT command “AT+CADC” to get the raw
data which is between 0 and 4095. The data can be transformed to any type such as voltage, temperature
etc. Please refer to document [1].
Figure 38: Reference circuit
Note: The input signal voltage value in ADC must not be higher than 2.2V.
SIM5320AL has a LDO power output, namely VREG_AUX. The LDO is available and output voltage is
2.85v by default, rated for 250mA. User can switch the LDO on or off by the AT command
“AT+CVAUXS” and configure its output voltage by the AT command “AT+CVAUXV”.
