For appli- cations where Q is significantly less than one, the maximum signal can be reduced. For example, if Q = 0.5, RFO2 = 100K and RQ = 50K, the signal at OUT1 will be twice OUT2 and will clip for large signals. By using the general equations, it can be seen that one solution to this problem would be to make RFO2 = RQ = 50K and RFO1 = 200K. INHPINPUT GND R1 RBP GND INBPINPUT
