description

™The LT 1259 contains two independent 130MHz current feedback amplifiers, each with a stop pin. These amplifiers are designed for excellent linearity while driving cables and other low-impedance loads. The LT1260 is a triple version, especially for RGB video applications. These amplifiers work on all materials from a single 5V to ± 15V, and when drawing only 5 mA per amplifier, the active is 5 mA. When turned off, the LT1259/LT1260 amplifier plots zero supply current, and its output becomes high impedance. Only two LT1260s require a full RGB 2-input multiplexer and cable driver. These amplifiers only have 100ns on and 40ns off, making them ideal for spread spectrum and portable device applications. The LT1259/LT1260 amplifiers are manufactured using Linear Technology's proprietary complementary bipolar process.
