The MAX4310–MAX4315 single-supply mux-amps com-
bine high-speed operation, low-glitch switching, and
excellent video specifications. The six products in this
family are differentiated by the number of multiplexer
inputs and the gain configuration. The MAX4310/
MAX4311/MAX4312 integrate 2-/4-/8-channel multiplex-
ers, respectively, with an adjustable gain amplifier opti-
mized for unity-gain stability. The MAX4313/MAX4314/
MAX4315 integrate 2-/4-/8-channel multiplexers, respec-
tively, with a +2V/V fixed-gain amplifier. All devices have
40ns channel switching time and low 10mVp-p switching
transients, making them ideal for video-switching applica-
tions. They operate from a single +4V to +10.5V supply,
or from dual supplies of ±2V to ±5.25V, and they feature
rail-to-rail outputs and an input common-mode voltage
range that extends to the negative supply rail.
The MAX4310/MAX4311/MAX4312 have a -3dB band-
width of 280MHz/345MHz/265MHz and up to a 460V/µs
slew rate. The MAX4313/MAX4314/MAX4315, with
150MHz/127MHz/97MHz -3dB bandwidths up to a
540V/µs slew rate, and a fixed gain of +2V/V, are ideally
suited for driving back-terminated cables. Quiescent sup-
ply current is as low as 6.1mA, while low-power shutdown
mode reduces supply current to as low as 560µA and
places the outputs in a high-impedance state. The
MAX4310–MAX4315’s internal amplifiers maintain an
open-loop output impedance of only 8Ω over the full out-
put voltage range, minimizing the gain error and band-
width changes under loads typical of most rail-to-rail
amplifiers. With differential gain and phase errors of
0.06% and 0.08°, respectively, these devices are ideal for
broadcast video applications.
