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 5m A per amplifier when active. When shut down, the LT1259/LT1260 amplifiers draw zero supply current and their outputs bee high impedance. Only two LT1260s are required to make a plete 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 plementary bipolar process. , LTC and LT are registered trademarks of Linear Technology Corporation.
