MAX4312：高速、低功耗、单电源、多通道、视频多路复用器-放大器

The MAX4310–MAX4315 single-supply mux-amps combine 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 multiplexers, respectively, with an adjustable gain amplifier optimized for unity-gain stability. The MAX4313/MAX4314/MAX4315 integrate 2-/4-/8-channel 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 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 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.
