Video

The OPA357 output stage is capable of driving standard back-terminated 75-Ω video cables, as shown in Figure 35. By back-terminating a transmission line, the cable does not exhibit a capacitive load to its driver. A properly back-terminated 75-Ω cable does not appear as capacitance; this cable presents only a 150-Ω resistive load to the OPA357 output.

The OPA357 can be used as an amplifier for RGB graphic signals, which have a voltage of zero at the video black level, by offsetting and AC-coupling the signal, as shown in Figure 36.

The source video signal offset is 300 mV above ground to accommodate the op amp swing-to-ground capability.
