The EL4093 is a complete DCrestoredvideo amplifier subsystem,featuring low power consumpTIon andhigh slew rate. It contains a current feedback amplifier and asample and hold amplifier designed to stabilize videoperformance. When the HOLD logic input is low, the sampleand hold may be used as a general purpose op amp to nullthe DC offset of the video amplifier. When the HOLD inputgoes high the sample and hold stores the correcTIon voltageon the hold capacitor to maintain DC correcTIon during thesubsequent video scan line.The sample and hold amplifier contains a current outputstage that greatly simplifies its connecTIon to the videoamplifier. Its high output impedance also helps to preservevideo linearity at low supply voltages. For ease of interfacing,the HOLD input is TTL-compatible. This device has anoperational temperature of -40°C to +85°C and is packagedin plastic 16-pin DIP and 16-pin SOIC.
