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.
