The analog peripherals allow the CC13x1x3 and CC26x1x3 to read and monitor sensors or perform other tasks and are directly controlled by the System CPU.
Some typical use cases may be (but not limited to) the following:
The Analog Peripherals include the following:
The ultra-low-power analog comparator can wake the CC13x1x3 and CC26x1x3 device platform from any active state. A configurable internal reference can be used with the comparator. The output of the comparator can also trigger an interrupt or trigger the ADC.
Capacitive sensing is not a stand-alone module in the CC13x1x3 and CC26x1x3 device platform; rather, the functionality is achieved through the use of a constant current source, a time to digital converter, and a comparator. The analog comparator in this block can also be used as a higher-accuracy alternative to the ultra-low-power comparator.
The ADC is a 12-bit, 200 ksps ADC with 8 inputs and a built-in voltage reference. The ADC can be triggered by many different sources including timers, I/O pins, software, the analog comparator, and the RTC.
An ADC is a peripheral that converts a continuous analog voltage to a discrete digital number. The ADC module features 12-bit conversion resolution and supports eight input channels plus an internal division of the battery voltage and a temperature sensor.
