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 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. The charge pump and
amplifiers can be placed in a power down mode, consuming
less than 1mA of current.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
