The MAX4090 is a 3V/5V, 6dB video buffer with sync-tip clamp and low-power shutdown mode. It is designed for driving DC-coupled, 150Ω back-terminated video loads in portable video applications such as digital still cameras, 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. It 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 it ideal for low-voltage, battery-powered video applications. The MAX4090 is available in tiny SOT23, SC70, and μDFN packages and is specified over the extended (-40°C to +85°C) and automotive (-40°C to +125°C) temperature ranges.
The MAX4090 video buffer from Maxim operates from a single 2.7 V to 5.5 V supply and consumes only 6.5 mA in normal mode. Its low‑power shutdown mode reduces the supply current to 150 nA, making it suitable for battery‑powered portable video applications such as digital cameras, DVD players, PDAs and video‑enabled cell phones.
The device provides a DC‑coupled output with a sync‑tip clamp that positions the video waveform at the output. It is available in space‑saving SOT23, SC70 and UDFN packages and is qualified for both commercial (‑40 °C to +85 °C) and automotive (‑40 °C to +125 °C) temperature ranges.
