Rev 1.00
March 5, 2007 200MHz Single Supply Video Driver With Charge Pump and Power Down
The ISL59837 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 ISL59837 generates the required negative
rail internally from a +3.3V power supply. This allows for
DC-accurate coupling of video onto a 75пЃ— 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. Features Ordering Information Amplifier enable/disable function control
