High-Speed, Low-Power, Single-Supply Multichannel, Video Multiplexer-Amplifiers

Product Details

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.

Description

The MAX4313 evaluation kit (EV kit) simplifies evaluation of the MAX4313 low-power, single-supply video multiplexer/amplifier. The MAX4313 is fixed to a gain of +2V/V, ideal for driving back-terminated cables. SMA connectors and 50Ω terminating resistors are included for 50Ω test equipment compatibility. Simply change the terminating resistors to 75Ω for video test equipment compatibility.

The EV kit comes with the MAX4313 installed. To evaluate the MAX4310, simply order a free sample (MAX4310ESA), replace the MAX4313 with the MAX4310 on the EV board, and change the gain-setting resistors for the desired gain.
