Why does ADA4528-2 have twice as much noise as OPA2188 in our circuit?

Question

According to the data sheets OPA2188 has more than twice the noise as ADA4528-2. But the test results are just the opposite. ADA4528-2 may have more current noise. But the calculated current noise cannot explain what observed.
