® Data Sheet January 1996, Rev B EL4093 FN7159 300MHz DC-Restored Video Amplifier The EL4093 is a complete DCrestored 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. The sample and hold amplifier contains a current output stage that greatly simplifies its connection to the video amplifier.
