3V/5V, 6dB Video Buffer with Sync-Tip Clamp
and 150nA Shutdown Current
General Description
The MAX4090 3V/5V, 6dB video buffer with sync-tip
clamp, and low-power shutdown mode is available in
tiny SOT23 and SC70 packages. The MAX4090 is
designed to drive DC-coupled, 150Ω back-terminated
video loads in portable video applications such as digi-
tal still cams, portable DVD players, digital camcorders,
PDAs, video-enabled cell phones, portable game sys-
tems, and notebook computers. The input clamp posi-
tions the video waveform at the output and allows the
MAX4090 to be used as a DC-coupled output driver.
The MAX4090 operates from a single 2.7V to 5.5V sup-
ply and consumes only 6.5mA of supply current. The
low-power shutdown mode reduces the supply current
to 150nA, making the MAX4090 ideal for low-voltage,
battery-powered video applications.
The MAX4090 is available in tiny 6-pin SOT23 and
SC70 packages and is specified over the extended
-40°C to +85°C temperature range.
