In back terminated video applications, bandwidth will only be limited by the RC time constants of the external output components. A minimum 10 pF capacitive load is required. When driving a 75Ω cable, place the 75Ω source termination resistor as close to the amplifier output as possible. Because the RC6302 is a voltage-feedback amplifier, it facilitates using reactive (capacitive and inductive) feedback components for implementing filters, integrators, sample/ hold circuits, etc. The feedback network and the parasitic capacitance at the inverting (summing junction) input create a pole and affect the transfer function of the circuit. For stable operation, minimize the parasitic capacitance and equivalent resistance of the components used in the feedback circuit. DC Accuracy Circuit Board Since the RC6302 is a voltage-feedback amplifier, the inverting and non-inverting inputs have similar impedances and bias currents. To minimize offset voltage, match the source resistances seen by inverting and non-inverting inputs. High-frequency applications require good grounding, power supply decoupling, low parasitic capacitance and inductance, and good isolation between the three inputs to minimize their crosstalk. Minimal coupling from output to input should exist to prevent positive feedback.
