General Description
The EL4093C is a complete DC-restored video amplifier subsystem, featuring low power consumption and high slew rate. It contains a current feedback amplifier and a sample and hold amplifier designed to stabilize video performance. When the HOLD logic input is low, the sample and hold may be used as a general purpose op amp to null the DC offset of the video amplifier. When the HOLD input goes high the sample and hold stores the correction voltage on the hold capacitor to maintain DC correction during the subsequent video scan line.
