Triple and Quad, 2:1 Video Multiplexer-
Amplifiers with Fixed and Settable Gain
General Description
Features
The MAX4023–MAX4026 family of voltage feedback
multiplexer-amplifiers combine low-glitch switching and
excellent video specifications with fixed or settable
gain. The MAX4024/MAX4026 are triple and quad 2:1
multiplexers, respectively, with amplifiers that have a
fixed gain of +2. The MAX4023/MAX4025 are triple and
quad 2:1 multiplexers, respectively, with adjustable
gain amplifiers optimized for unity-gain stability. All
devices have 25ns channel switching time and low

high-speed video-switching applications. These
devices operate from a single +4.5V to +11V supply or
from dual supplies of 2.25V to 5.5V, and feature an
input common-mode voltage range that extends to the
negative supply rail. A low-power disable mode places
the output in a high-impedance state.

The MAX4023/MAX4025 have -3dB bandwidths of
260MHz and up to 330V/µs slew rates with a settable
gain to equalize long cable runs. The MAX4024/
MAX4026, with 200MHz -3dB bandwidths and 363V/µs
slew rates, have a fixed gain of +2 for driving short
back-terminated cables. The MAX4023/MAX4025 inter-
nal amplifiers maintain an open-loop output impedance
of only 18Ω over the full output voltage range, and mini-
mize the gain error and bandwidth changes under
loads typical of most Rail-to-Rail® amplifiers. These
devices are ideal for broadcast video applications with
differential gain and phase errors of 0.07% and 0.07°,
respectively.
