250mA Minimum Output Drive Current
TheLT®1206isacurrentfeedbackamplifierwithhighoutput
currentdrivecapabilityandexcellentvideocharacteristics.
The LT1206 is stable with large capacitive loads, and can
easily supply the large currents required by the capacitive
loading. A shutdown feature switches the device into a
high impedance, low current mode, reducing dissipation
when the device is not in use. For lower bandwidth ap-
plications, the supply current can be reduced with a single
external resistor. The low differential gain and phase, wide
bandwidth, and the 250mA minimum output current drive
make the LT1206 well suited to drive multiple cables in
video systems.
