DescripTion
The LT
current drive capability and excellent video characteristics.
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.
The LT1206 is manufactured on Linear Technology’s pro-
prietary complementary bipolar process.
