MAX4090 3V / 5V, 6dB video buffer with sync head clamp

MAX4090 3V / 5V, 6dB video buffer with sync head clamp and 150nA shutdown current

Overview

The MAX4090 is a 3V / 5V powered 6dB video buffer with sync head clamping and low-power shutdown mode. The chip is available in SOT23 and SC70 packages. The MAX4090 is designed to drive DC-coupled, 150Ω back-terminated video loads in portable video equipment, such as digital cameras, portable DVD players, portable digital camcorders, PDAs, cellular phones with video capabilities, portable game consoles, and notebook computers. . Input clamping can locate the output video waveform, making the MAX4090 output driver both DC-coupled.

The MAX4090 uses a single power supply from 2.7V to 5.5V and consumes only 6.5mA of supply current. The low-power shutdown mode reduces the supply current to 150nA, which makes the MAX4090 ideal for low-voltage, battery-powered video equipment.

The MAX4090 is available in tiny, 6-pin SOT23, SC70, and µDFN packages, and operates over the -40 ° C to + 85 ° C extended temperature range and the -40 ° C to + 125 ° C automotive temperature range.
