250mA/60MHz Current
Feedback Amplifier
The LT
®
1206 is a current feedback amplifier with high output
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 Technologys pro-
prietary complementary bipolar process.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Applies to short circuits to ground only. A short circuit between
the output and either supply may permanently damage the part when
operated on supplies greater than ±10V.
