The Tykes have won two of their last three league matches to put last month's miserable four-game losing streak behind them.
Davey said: "Cardiff City are a side going for promotion. They're a good team with some excellent players who perform in an effective way.
"We have to go there and stop that and try to get a result. I'm confident we can go there and get a win that we need more than them.
"We will look to go to Cardiff and quieten their supporters, frustrate them and come away with a victory."
