MAX4032EUT+T

P1-P3P4-P6P7-P9P10-P10
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
