so plz help me if possible
They are quite old devices (and the AD705J is obsolete). The best way to find an alternative is to use the manufacturers web site to select a new one using a few key parameters from the old device e.g. offset, input bias current, bandwidth, noise.
Or have a look at some of the other discussions on ECG circuits on the EDA Board.
