The ISL59837 is a revolutionary device that allows true singlesupply operation of video amplifiers. ISL59837是一个革命性的设备，使真正的单电源放大器的视频操作。 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.对于需要输出摆幅，但缺乏地下负电源系统设计，ISL59837生成所需的负电源内部采用+3.3 V电源。 This allows for DC-accurate coupling of video onto a 75Ω double-terminated line.这允许直流耦合视频精确到一个75Ω双行终止。 The buffers have an integrated 6dB, eliminating the need for external gain-setting resistors.该缓冲器具有集成为6dB，无需外部增益设置电阻器的需要。 An external reference voltage can be applied to the REF pin to shift the analog video level down by the desired amount.外部参考电压可被应用到REF引脚转移所需数量的模拟视频电平下来。 The charge pump and amplifiers can be placed in a power down mode, consuming less than 1mA of current.电荷泵和放大器可放置在掉电模式下，消耗电流小于1mA的。
