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, 150 back-terminated video loads in portable video applications such as digital still cams, portable DVD players, digital camcorders, PDAs, videoenabled 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 330F ACcoupling capacitor to two small, less expensive 22F 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, batterypowered video applications. The MAX4032 is available in tiny 6-pin SOT23 and SC70 packages and is specified over the extended -40C to +85C temperature range. |
