ISL59830
May 4, 2006
FN7489.6
True Single Supply Video Driver
The ISL59830 is a revolutionary device that allows true single-
supply operation of video amplifiers. The device runs off a
single 3.3V supply and generates the required negative
voltage internally. This allows for DC-accurate coupling of
video onto a 75Ω double-terminated line. Since the buffers
have an integrated 6dB gain, no external gain setting resistors
are required. An input reference voltage can be supplied to
shift the analog video level down by an amount equal to the
reference (typically 0.6V).
Features
• Triple single-supply buffer
• Operates from single +3.3V supply
• No output DC blocking capacitor needed
• Fixed gain of 2 output buffer
• Output three-statable
• Enable/disable function
• 50MHz 0.1dB bandwidth
• 200MHz -3dB bandwidth

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.
