This circuit is designed for cases where very accurate offset adjustments must be made. Coarse adjustment is provided by the offset pot at pins 9/10.The output of the 2920 is returned to the input (at pin 7), an LF356H op amp to provide soft offset correction automatically. This circuit is recommended when processing bipolar or low duty-cycle pulse signals. Rin, should match the source impedance. C2 is typically between 10 and 50 pF.
