DescriptionThe MAX4023MAX4026 family of voltage feedback multiplexer-amplifiers combine low-glitch switching and excellent video specifications with fixed or settable gain. The MAX4024/MAX4026 are triple and quad 2:1 multiplexers, respectively, with amplifiers that have a fixed gain of +2. The MAX4023/MAX4025 are triple and quad 2:1 multiplexers, respectively, with adjustable gain amplifiers optimized for unity-gain stability. All devices have 25ns channel switching time and low 10mVP-Pswitching transients, making them ideal for high-speed videoswitchingapplications. These MAX4025 operate from a single +4.5V to +11V supply or from dual supplies of ±2.25V to ±5.5V, and feature an input common-mode voltage range that extends to thenegative supply rail. A low-power disable mode places the output in a high-impedance state.
The MAX4023/MAX4025 have -3dB bandwidths of 260MHz and up to 330V/µs slew rates with a settable gain to equalize long cable runs. The MAX4024/ MAX4026, with 200MHz -3dB bandwidths and 363V/µs slew rates, have a fixed gain of +2 for driving short back-terminated cables. The MAX4023/MAX4025 inter- nal amplifiers maintain an open-loop output impedanceof only 18Ωover the full output voltage range, and mini- mize the gain error and bandwidth changes under loads typical of most Rail-to-Rail®amplifiers. These MAX4025 are ideal for broadcast video applications with differential gain and phase errors of 0.07% and 0.07°, respectively.
