Maxim MAX497CSE, MAX497CPE, MAX497C-D, MAX496CPE, MAX496C-D Datasheet

________________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 slew­rate 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.
