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.
