General Description

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 18

Ω over the full output voltage range, and mini-

mize the gain error and bandwidth changes under

devices are ideal for broadcast video applications with

differential gain and phase errors of 0.07% and 0.07°,

respectively.
