5V, 6dB Video Buffer with Sync-Tip Clamp,

Output Sag Correction, and 150nA Shutdown Current

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 intro-

duces 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 wave-

form 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.
