Applications Discussion
Capacitive Load
The RC6333 can drive a capacitive load from 10 to over 50 pF. In back terminated video applications, bandwidth will only be limited by the RC time constants of the external output components. When driving a 75W cable, place the 75W source termination resistor as close to the amplifier output as possible.
Feedback Components
Because the RC6333 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
Since the RC6333 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.
Circuit Board
High-frequency applications require good grounding, power supply decoupling, low parasitic capacitance and inductance, and good isolation between the inputs to minimize their crosstalk. Avoid coupling from output to input to prevent positive feedback.
