225MHz, Triple, 2-Channel Video
Multiplexer-Amplifier
General Description
The MAX4027 is a triple, wideband, 2-channel, nonin-
verting gain-of-two video amplifier with input multiplex-
ing, capable of driving up to two back-terminated video
loads. The MAX4027 features current-mode feedback
amplifiers configured for a gain of two (+6dB) with a
-3dB large-signal bandwidth of 200MHz. The device
has low (0.012%/0.014°) differential gain and phase
errors, and operates from ±5V supplies.
The MAX4027 is ideal for use in broadcast and graph-
ics video systems because of the low 2pF input capaci-
tance, channel-to-channel switching time of only 15ns,
and wide 62MHz, large-signal 0.1dB bandwidth. High-
impedance output disabling allows the MAX4027 to be
incorporated into large switching arrays with minimal
interaction with the source. Specified over the -40°C to
+85°C extended temperature range, the MAX4027 is
available in 14-pin SO and TSSOP packages.
