... Choosing Resistor Values Unity-Gain Configurations The MAX4265 and MAX4268 are internally compensat- ed for unity gain. When configured for unity gain, they require a small resistor ( series with the feedback F path (Figure 1). This resistor improves AC response by reducing the Q of the tank circuit, which is formed by parasitic feedback inductance and capacitance ...
