If the video does not contain any AC components during the
autozero level (e.g. RGB video), then the above networks
are not needed and the CFA output can be connected
directly to the S/H input.
Power Dissipation
The EL4093 current feedback amplifier has an absolute
maximum of ±30mA output current drive. This is slightly
more than the current required to drive ±2V into 75Ω. To see
how much the junction temperature is raised in this worst
case, we refer to the equations below:

assume that it is at maximum current swing (±5.5mA) but at
a mid-rail output voltage (0V). With the above assumptions,

resistance of a narrow SO package (120°C/W), this yields a
temperature increase of 27°C. Since the maximum ambient
temperature is 85°C, the resulting junction temperature of
112°C is still below the maximum.
