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 digital still cams, portable DVD players, digital camcorders, PDAs, video-enabled cell phones, portable game systems, and notebook computers. The input clamp positions 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 supply 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 and µDFN packages and is specified over the extended (-40°C to +85°C) and automotive (-40°C to +125°C) temperature ranges.
