7.3.5 Video

The OPAx354 output stage is capable of driving standard back-terminated 75Ω video cables, as shown in Figure 7-3. By back-terminating a transmission line, the output stage does not exhibit a capacitive load to the driver. A properly back-terminated 75Ω cable does not appear as capacitance; the cable presents a 150Ω resistive load to the OPAx354 output.

The OPAx354 is used as an amplifier for RGB graphic signals, which feature a voltage of zero at the video black level, by offsetting and AC-coupling the signal. See Figure 7-4.
