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.
