________________General Description

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 are not slew-

rate limited, thus providing a high full-power bandwidth

of 230MHz and 215MHz, respectively.

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.
