Supports SPI® interfaces

I need HELP!! I don't find anything in this direction. :(

Best regards

    Hi Timo,

    Unfortunately, there isn't a product within our Precision Analog catalog that can meet all of your requirements. The wide bandwidth and 3.3 V requirements eliminate the one product that comes closest to satisfying the requirement, the PGA2505 which is actually a PGA intended for microphone applications. The bandwidth, supply voltage, or SPI requirement pretty well eliminates anything else I could propose.

    I checked the High-Speed product offerings but didn't find any product that satisfies all your requirements. Since this is a wide-band application you may want to re-post your inquiry to the E2E High Speed Amplifiers forum. The engineers who support that forum are much more familiar with their product line and may have some product suggestions that I haven't uncovered.

    Regards, Thomas
