General Description

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.

MAX4310–MAX4315 High-Speed, Low-Power, Single-Supply Multichannel, Video Multiplexer-Amplifiers Digital Interface The multiplexer architecture of the MAX4310–MAX4315 ensures that no two input channels are ever connected together. Channel selection is accomplished by applying a binary code to channel address inputs. The address decoder selects input channels, as shown in Table 2. All digital inputs are CMOS compatible.
