Description

The RC6302 consists of two low power, wide band voltage feedback operational amplifiers. Each channel is capable of delivering a load current of at least 35mA. The amplifiers are optimized for video applications where low differential gain and low phase distortion are significant requirements.

RC6302 PRODUCT SPECIFICATION Applications Discussion Capacitive Load The RC6302 can drive a capacitive load from 10 to over 100 pF. In back terminated video applications, bandwidth will only be limited by the RC time constants of the external out- put components. A minimum 10 pF capacitive load is required. When driving a 75W cable, place the 75W source termination resistor as close to the amplifier output as possible. DC Accuracy Since the RC6302 is a voltage-feedback amplifier, the invert- ing 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. Feedbac k Components Because the RC6302 is a voltage-feedback amplifier, it facil- itates 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 sta- ble operation, minimize the parasitic capacitance and equiva- lent 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 three inputs to minimize their crosstalk. Minimal coupling from output to input should exist to prevent positive feedback.
