Hi Arye,

Unfortunately the only analog switches we have that are characterised at +/-20V are the ADG5412/13 and ADG5212/13.

Hello OliverSedlacek,

I believe the quickest and easiest method would be to use the ADG1212 spice model and change the model values to that from the ADG5212 data sheet. This might not produce the exact result as required, but it will give you a good…

Hi Vincent,

You know our parts well then!  Nice to hear that.  Yes, the ADG5212 is very different from the AD75019, I mentioned it just as an example.  We don't have Ron plots for the much older AD75019 unfortunately.  As you say if you are going through…

Hi Jacky,

Analog Devices has a wide variety of switches/multiplexer. If you are looking for a switches/multiplexer with supply voltage that can withstand +/-16V and has an off isolation greater than -48dB at 30Mhz, you may want to look at ADG5212,ADG5213…

Hi imanjohn,

Have you any more details on what the fault is that is damaging the part? Is it a positive or negative over voltage condition?

I have attached a tutorial which outlines protection methods to be used. You have implemented one of them but…
