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.
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 electromagnetic
interference (EMI).

Figure 2.
The AD8142 includes a unique sync-on-common-mode feature
that 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-
line, and the AD8117 or AD8175 crosspoint switches to produce
a high resolution video distribution system.
