The LT
®
1259 contains two independent 130MHz current
feedback amplifiers, each with a shutdown pin. These
amplifiers are designed for excellent linearity while driving
cables and other low impedance loads. The LT1260 is a
triple version especially suited to RGB video applications.
These amplifiers operate on all supplies from single 5V to
±15V
and draw only 5mA per amplifier when active.
When shut down, the LT1259/LT1260 amplifiers draw
zero supply current and their outputs become high
impedance. Only two LT1260s are required to make a
complete 2-input RGB MUX and cable driver. These
amplifiers turn on in only 100ns and turn off in 40ns,
making them ideal in spread spectrum and portable
equipment applications.
The LT1259/LT1260 amplifiers are manufactured on
Linear Technology’s proprietary complementary bipolar
process.
