The EL4089 is an 8-pin complete DCrestoredmonolithic video amplifiersub-system. It contains a high qualityvideo amplifier and a nulling, sample-and-hold amplifierspecifically designed to stabilize video performance.When the HOLD logic input is set to a TTL/CMOS logic 0,the sample - and - hold amplifier can be used to null the DCoffset of the video amplifier.When the HOLD input goes to a TTL/CMOS logic l, thecorrecTIng voltage is stored on the video amplifier’s inputcoupling capacitor. The correcTIon voltage can be furthercorrected as need be, on each video line.
