AD8142ACPZ

GENERAL DESCRIPTION

The AD8141 and AD8142 are triple, low cost, differential or single-ended- input-to-differential-output drivers. Each amplifier has a fixed gain of 2 to compensate for the attenuation of the line termination resistors. The AD8141 and AD8142 are specifically designed for RGB signals but can be used for any type of signals. The amplifiers have very fast slew rate and settling time while being manufactured on a cost effective CMOS process. They are optimized for high resolution video performance with a 0.1 dB flatness of 65 MHz, which allows driving high resolution video over any type of UTP cable.
