MILPITAS, Calif., Nov. 30, 1995 -- élantec Semiconductor, Inc., (NASDAQ:ELNT) today expanded its family of DC restore video amplifiers with the introduction of the EL4093, a complete DC-restored video amplifier subsystem designed for a broad range of video equipment and multimedia PC cards.
Now available in samples, the EL4093 contains a current feedback amplifier and a sample and hold amp designed to stabilize video performance, featuring a very fast enable and low leakage. The device provides a 300 MHz bandwidth and 1500V/µ s slew rate using a low typical supply currentof 9.5 mA. Differential gain is 0.04%; differential phase is 0.02° into 150 ohms for NTSC-compatible systems. The EL4093 runs on ± 5V power supplies.
The sample-and-hold amp contains a current output stage that simplifies its connection to the video amp. Its high output impedance also helps preserve video linearity at low supply voltages.
The new EL4093 is ideal for video mixing equipment, video descramblers, and multimedia cards for PCs, according to Ralph Granchelli, Vice President of Marketing. It also provides the level of performance required for new studio equipment now being developed for high definition television (HDTV), and for the new generation of super video graphics adapter cards now being manufactured.
"The EL4093 provides excellent overall performance at 5 Volts," Granchelli said. "Demand for this type of DC restore amplifier has been rising steadily since we introduced our first dedicated DC restore amplifier in 1990, and new applications are coming on line as designers begin or continue work on new studio equipment for HDTV." Granchelli added that élantec Semiconductor is at work now on a complete family of DC restore amps that are lower priced and have lower power requirements.
The EL4093 is available now in 16-pin plastic DIP samples for $7.45 each.
