OPA3875 Triple 2-to-1 High-Speed Video Multiplexer
The OPA3875 offers a very wideband, 3-channel, 2:1 multiplexer in a small SSOP-16 package. Using only 11mA/ch, the OPA3875 provides three, gain of +2, video amplifier channels with greater than 400MHz large-signal bandwidth (4VPP). Gain accuracy and switching glitch are improved over earlier solutions using a new (patented) input stage switching approach. This technique uses current steering as the input switch while maintaining an overall closed-loop design. Gain matching between each of the 3-channel pairs is also significantly improved using this technique (<0.2% gain mismatch). With greater than 700MHz small-signal bandwidth at a gain of 2, the OPA3875 gives a typical 0.1dB gain flatness to greater than 150MHz.
