... Data Sheet 200MHz Single Supply Video Driver With Charge Pump and Power Down The ISL59837 is a revolutionary device that allows true single- supply operation of video amplifiers. Designed for systems requiring output swing below ground but lacking a negative power supply, the ISL59837 generates the required negative rail internally from a +3.3V power supply. This allows for DC-accurate coupling of video onto a 75Ω ...
