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

The drivers have an internal common-mode feedback loop that provides output amplitude and phase matching, achieving−50 dB balance error at 50 MHz and thereby suppressing even-order harmonics and minimizing radiated electromagneticinterference (EMI).

The AD8142 includes a unique sync-on-common-mode featurethat allows the user to transmit balanced horizontal and vertical video sync signals over the three common-mode channels.Additionally, the AD8141 and AD8142 both have a disable feature that, when asserted, produces high-Z outputs, allowing line isolation and easy multiplexing.

The AD8141 and AD8142 are available in a 24-lead 4 mm × 4 mm LFCSP and operate over a temperature range of −40°C to +85°C.They can be used with the AD8145 triple differential-to-single-ended receiver, AD8123 triple equalizer, AD8120 triple delayline, and the AD8117 or AD8175 crosspoint switches to producea high resolution video distribution system.
