The MAX496 and MAX497 are quad, closed-loop, ±5V video buffers that feature extremely high bandwidth and slew rate for both component video (RGB or YUV) and composite video (NTSC, PAL, SECAM). The MAX496 is a unity-gain (0dB) buffer with a 375MHz -3dB bandwidth and a 1600V/µs slew rate. The MAX497 gain of +2 (6dB) buffer, optimized for driving back-terminated coaxial cable, features a 275MHz -3dB bandwidth and a 1500V/µs slew rate. The MAX496/MAX497 incorporate a unique two-stage architecture that combines the low offset and noise benefits of voltage feedback with the high bandwidth and slew-rate advantages of current-mode-feedback.
The MAX496 and MAX497 are quad, closed‑loop video buffer amplifiers designed for component (RGB or YUV) and composite video applications. They provide very high bandwidth and slew‑rate performance, with the MAX496 offering a unity‑gain (+1 V/V) configuration and the MAX497 a fixed gain of +2 V/V.
These devices are intended for use in computer workstations, surveillance video, broadcast and high‑definition TV systems, multimedia products, medical imaging, high‑speed signal processing, video switching and routing, and other high‑performance video applications. The datasheet details electrical characteristics, pin configurations, layout recommendations, and package options.
