General Description
The MAX4310–MAX4315 single-supply mux-amps com-
bine high-speed operation, low-glitch switching, and excel-
lent video specifications. The six products in this family are
differentiated by the number of multiplexer inputs and the
gain configuration. The MAX4310/MAX4311/MAX4312 inte-
grate 2-/4-/8-channel multiplexers, respectively, with an
adjustable gain amplifier optimized for unity-gain stability.
The MAX4313/MAX4314/MAX4315 integrate 2-/4-/8-chan-
nel multiplexers, respectively, 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 applications. They operate from a sin-
gle +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 bandwidth
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 supply 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 output voltage range, minimizing the gain
error and bandwidth 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.
