♦ MAX496 Fixed Gain: +1V/V
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
c a b le , fe a ture s a 275MHz -3d B b a nd wid th a nd 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.
MAX497 Fixed Gain: +2V/V
♦ High Speed:
Small-Signal -3dB Bandwidth: 375MHz (MAX496)
275MHz (MAX497)
Full-Power -3dB Bandwidth: 230MHz (MAX496)
215MHz (MAX497)
♦ 0.1dB Gain Flatness: 65MHz (MAX496)
120MHz (MAX497)
♦ 1600V/µs Slew Rate (MAX496)
1500V/µs Slew Rate (MAX497)
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.
♦ Fast Settling Time: 12ns to 0.1%
♦ Lowest Differential Phase/Gain Error: 0.01°/0.01%
♦ 2pF Input Capacitance
♦ 5.6nV/√Hz Input-Referred Voltage Noise
♦ Low Distortion: 64dBc (f = 10MHz)
♦ Directly Drives 50Ω or 75Ω Back-Terminated Cables
♦ High ESD Protection: 5000V
