The ISL59833 is a revolutionary device that allows true singlesupply operation of video amplifiers. Designed for systems

requiring output swing below ground but lacking a negative

power supply, the ISL59833 generates the required negative

rail internally from a +3.3V power supply. This allows for

DC-accurate coupling of video onto a 75Ω double-terminated

line. The buffers have an integrated 6dB, eliminating the need

for external gain-setting resistors. An external reference

voltage can be applied to the REF pin to shift the analog video

level down by the desired amount.
