The DG419 looks into the high input impedance of the op amp, so the effects of RDS(on) are negligible.The DG441 is also connected in series with RIN and is not included in the feedback dividers, thus contributing negligible error to the overall gain. Because the DG419 and DG441 can handle ±15 V, the unity gain follower connection, X1, is capable of the full op-amp output range of ±12 V.
