“Analog Devices’ newly enhanced video filter and amplifiers enable engineers to deliver sharper, more lifelike images in high-resolution analog video formats,” said Bill Bucklen, director, Advanced Television Segment, Analog Devices. “These compact, single-chip solutions reduce design complexity while eliminating costly system redesign in HD video applications especially where a video filter is required to decode standard-definition content or a high-speed amplifier is needed to optimize screen images for 1080i or 1080p.”
Enhanced HD Performance
The ADA4855-3 and ADA4856-3 triple, rail-to-rail output video amplifiers deliver the best combination of speed and performance in their class, making them ideal for consumer and professional video devices that require the highest bandwidth and the widest output voltage range in order to deliver superior analog video performance. Offering unit costs that are comparable with more complex, lower bandwidth rail-to-rail output video amplifiers, the ADA4855-3 and ADA4856-3 are ideal for high-resolution video applications that require lossless 1080i, sharper 1080p analog output video and a wide output swing. The video amplifiers also can be used as analog video buffers in all video output devices, such as PCs, monitors, projectors and DVD players, eliminating the need for discrete components.
The ADA4855-3 and ADA4856-3 provide single-supply, rail-to-rail operation with greater flexibility for passing a wide range of signals, while reducing system cost and complexity. The devices deliver advanced video performance, driving a 150-ohm load with 0.01 percent differential gain error, 0.01 degrees differential phase error and 0.1-dB flatness out to 63 MHz and 85 MHz, respectively. In addition, the ADA4855-3 offers a wide 400-MHz 3-dB bandwidth at gain of 1, while the ADA4856-3 delivers 220
