    Hi,

    referring to the device datasheet - http://www.ti.com/lit/ds/symlink/cc1111f32.pdf, chapter 12.5.1 "DMA Operation": 

    "There are five DMA channels available in the DMA controller numbered channel 0 to channel 4.", and Table 51: "DMA Trigger Sources", you can see that both RF radio RX/TX and ADC operation can be used as trigger. So basically the answer to your question is "yes", as you can assign different channel for both DMA operations from radio and ADC.
