AD 8231: input bias current return path

Question asked by bcr on Mar 31, 2016

According to the data sheet, it is good practice to include a return path for the input bias current. I have implemented the capacitive coupled approach (Fig 51) without good results. What are the recommended values for R and C for a single-supply voltage (+Vs, 0) and should I connect both resistors to Vref or another voltage other than ground? Thanks.
