Product Summary
The OPA3875IDBQ is a Triple 2:1 High-Speed Video Multiplexer. The OPA3875IDBQ offers a very wideband, 3-channel, 2:1 multiplexer in a small SSOP-16 package. Using only 11mA/ch, the OPA3875IDBQ provides three, gain of +2, video amplifier channels with > 400MHz large-signal bandwidth (4V PP ). 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 >700MHz small-signal bandwidth at a gain of 2, the OPA3875IDBQ gives a typical 0.1dB gain flatness to > 150MHz. The applications of the OPA3875IDBQ are (1)RGB switching; (2)LCD projector input select; (3)workstation graphics; (4)triple ADC input mux; (5)drop-in upgrade to LT1675/
