lasted 8 samples are compared and averaged to provide a stable and valid result.
In Sleep mode, the ADC is stopped. When the G610 switch to Idle mode, the ADC should be
stable after 5mS.
3.10.1 Power Supply ADC
The main power supply (BATT) is sampled internally by the G610 ADC interface through a
dedicated input, which is not accessible on the interface connector. The G610 constantly monitors
the power supply for any low or high voltage.
Parameter Conditions Min Typ Max Unit
Supply Range Operating range 3.20 4.50 V
Resolution 1.0 %
Sampling Time 16 KHz
The ADC signals operation and reporting mechanism is defined by the AT+CBC command.
3.10.2 General Purpose ADC
The G610 provides 2 general purpose ADC signal for customer application use. The ADC
signal can monitor a separate external voltage and report its measured level independently to the
application, through the AT command interface.

The ADC signals operation and reporting mechanism is defined by the AT+MMAD command.
3.11 Controls and Indicators Interface
The G610 incorporates several interface signals for controlling and monitoring the module's
operation. The following paragraph describes these signals and their operation.
