After triggering TASK_STOP, try to wait for EVENTS_STOPPED before disabling the SAADC.

Snippet:

    nrf_saadc_task_trigger(NRF_SAADC_TASK_STOP);

    // Wait for ADC being stopped.
    bool result;
    NRFX_WAIT_FOR(nrf_saadc_event_check(NRF_SAADC_EVENT_STOPPED), HW_TIMEOUT, 0, result);
    NRFX_ASSERT(result);
