amplifiers are designed for excellent linearity while driving ■ High Slew Rate: 1600V/µs cables and other low impedance loads. The LT1260 is a ■ Wide Supply Range: ±2V(4V) to ±15V(30V) triple version especially suited to RGB video applications. ■ 60mA Output Current These amplifiers operate on all supplies from single 5V to ■ Low Supply Current: 5mA/Amplifier ±15V and draw only 5mA per amplifier when active. ■ Differential Gain: 0.016% When shut down, the LT1259/LT1260 amplifiers draw ■ Differential Phase: 0.075° zero supply current and their outputs become high ■ Fast Turn-On Time: 100ns impedance. Only two LT1260s are required to make a ■ Fast Turn-Off Time: 40ns complete 2-input RGB MUX and cable driver.
