I'm perfoming a noise analysis in LTSpice. My circuit includes the ADG749, therefore I downloded the provided Spice model (.cir), and created an appropriate symbol in LTSpice (which I have already done several times).
By performing my noise…
There are several ".subckt....... .ends" blocks in the ADG749 spice model.
Contact Cadence as to why they don't recognize them.
I want to use the ADG749 analog switch for a AC signal in the 60kHz range. I don't have any DC offset so the AC will go negative. The datasheet says the analog signal range is 0 to VDD. This sounds like I can't use an analog switch for AC signals…
