5V, 6dB Video Buffer with Sync-Tip Clamp, Output Sag Correction, and 150nA Shutdown Current

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.

The MAX4032 operates from a single +5V supply and consumes only 6.5mA of supply current. The low-power shutdown mode reduces the supply current to 150nA, making the MAX4032 ideal for low-voltage, battery-powered video applications.

The MAX4032 is available in tiny 6-pin SOT23 and SC70 packages and is specified over the extended -40°C to +85°C temperature range.
