概述
The LT6555CGN is a high speed triple 2:1 video multiplexer with an internally fixed gain of 2. The individual amplifiers are optimized for performance with a double terminated 75Ω video load and feature a –3dB 2VP-P bandwidth of 450MHz, making them ideal for driving very high resolution video signals. Separate power supply pins for each amplifier boost channel separation to 72dB, allowing the LT6555CGN to excel in many high speed applications.
While the performance of the LT6555CGN is optimized for dual supply operation, it can also be operated with a single supply as low as 4.5V. Using dual 5V supplies, each amplifier draws only 9mA. When disabled, the amplifiers draw less than 500μA and the outputs become high impedance.
The LT6555CGN is manufactured on our proprietary low voltage complementary bipolar process and is available in 24-lead SSOP and ultra-compact 24-lead QFN packages.
