MAXIM MAX4023, MAX4026 Technical data

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
10mV

P-P

switching transients, making them ideal for
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 inter­nal amplifiers maintain an open-loop output impedance
of only 18Ω over the full output voltage range, and mini­mize 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.

ABSOLUTE MAXIMUM RATINGS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
