Applications Discussion
Capacitive Load
The RC6334 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 RC6334 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 RC6334 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.
