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.

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.

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.

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.
