Flight Crew Took Evasive Action
In this opportunity let me submit the following report to inform about the event TCAS/RA from the Flight into DEN. On our approach to Denver's airport we were given radar vectors from the right to land at runway 16R; everything was going as usual; on the last Vectors to intercept final approach  the controller asked us if we had the field insight to complete visual (we were completely on a visual condition) to runway 36R so we answer YES could make a VMC approach to runway 36R; she also told us that simultaneously approaches where in progress to runway 16L and she ask us if we had a Boeing 737 in sight (to our left) with the traffic being  100% insight we gave the controller the traffic insight. We intercept final and suddenly the TRAFFIC  alert system detected the other airplane so IT gave the Advisory TRAFFIC; TRAFFIC  like 3 or 4 seconds later gave the Resolution Advisory DESCEND; DESCEND I performed the maneuver by disconnecting the AP and descending to successfully perform the maneuver. I calculate approximately we were 1800 ft AGL and the maneuver lead us to lose about 400 ft until we heard the respective 'CLEAR OF CONFLICT 'of the airplane system; after that I just level the airplane to recover the flight path and landed with normal procedures. I would like to add to the report that all the time we has visual contact with the other traffic; what my logic takes me to; was that both systems sensed we were going to make the impact because of the proximity; time and speed of both aircraft but we were VMC all the time with the separation to the parallel runway. In conclusion they are still machines that's why they sense such events.
A320 crew received an RA while on a parallel approach. Uneventful landing completed after 'Clear of Conflict.'
