Application Information

Contd

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 01 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 b035V so that the

entire video span encompasses g035V rather

than the unrestored possible span of g07V (for

standard-sized signals) For the preceding leveler

circuit the black level should be set more toward

07V to accommodate the largest input

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 mul-

tiplier
