The OPA875 offers a very wideband, single-channel2:1 mulTIplexer in an SO-8 or a small MSOP-8package. Using only 11mA, the OPA875 provides again of +2 video amplifier channel with greaterthan 425MHz large-signal bandwidth (4V PP ). Gainaccuracy and switching glitch are improved overearlier soluTIons using a new input stage switchingapproach. This technique uses current steering as theinput switch while maintaining an overall closed-loopdesign. With greater than 700MHz small-signalbandwidth at a gain of 2, the OPA875 gives a typical0.1dB gain flatness to greater than 200MHz.System power may be reduced using the chip enablefeature for the OPA875. Taking the chip enable linehigh powers down the OPA875 to less than 300 µ Atotal supply current. Muxing mulTIple OPA875 outputstogether, then using the chip enable to select whichchannels are acTIve, increases the number of possible
