LT1259 - Low Cost Dual and Triple 130MHz Current Feedback Amplifiers with Shutdown - Linear Technology（凌力尔特）

功能描述

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.
