Although another amplifier is needed to gain the output back
to standard level, the reduced error currents bring the
differential phase error to less than 0.1 over the entire input
range.
A useful technique to reduce video distortion is to DC-
restore the video level going into the EL4095, and offsetting
black level to -0.35V so that the entire video span
encompasses ±0.35V rather than the unrestored possible
span of ±0.7V (for standard-sized signals). For the preceding
leveler circuit, the black level should be set more toward
-0.7V to accommodate the largest input, or made to vary

with the gain control itself (large gain, small offset; small
gain, larger offset).
The EL4095 can be wired as a four quadrant multiplier:
