General Description
The MAX4032 5V, 6dB video buffer with sync-tip clamp, output sag correction, and low-power shutdown mode is available in tiny SOT23 and SC70 packages. The sag-corrected output of the MAX4032 is designed to drive AC-coupled, 150Ω back-terminated video loads in portable video applications such as digital still cams, portable DVD players, digital camcorders, PDAs, video enabled cell phones, portable game systems, and notebook computers. The sag correction feature introduces low-frequency compensation that reduces the value of the normally bulky and expensive 330µF AC coupling capacitor to two small, less expensive 22µF capacitors. The input clamp positions the video waveform at the output and allows the MAX4032 to be used as either an AC- or DC-coupled output driver.
