This is a Digital Programmable Exactness Amplifier Circuit Diagram. In this circuit the DG419looks into the high input impedance of the op amp, so the effects of Rvs(o`l are negligible. The DG441 is also connected in series with RIN and is not included in the feedback dividers, thus contributing negligible.

Because the DG419 and DG441 can handle Â±15 V, the unity gain follower connection, Xl, is capable of the full op-amp output range of Â± 12 V. Read: Low Distortion Amplifier cum Compressor Circuit Diagram
