Amplifier eliminates negative supply

A novel triple video amplifier for single-supply applications features a wide output swing that extends to 0.8V of supply rails. As a result, the wideband RGB amplifier can provide full video swing when operated from a 5V single supply.

Linear Technology’s LT6557 features -3dB bandwidth of 500MHz and a fast slew rate of 2200V/μs coupled with a quick 4ns settling time. As a result, it enhances ac performance of the amplifier, resulting in sharper video images. In addition, the LT6557 maintains a 0.1dB gain flatness.
