There is no spice model available for the ADG1409. The spice models we have available are at this site http://www.analog.com/en/tools-software-simulation-models/resources/index.html
Please send a copy of your schematic for review.
I want to switch two power supply (+5V and +12V) with an ADG1409 mux to 4 differents outputs. Please see attached image.
I use U15 to select the power supply. With A0_1 == A1_1 == 0 in DA pin I will have +5V, and with A0_1 == 0 nad A1_1 == 1…
I have a problem with this circuit. I'm using this circuit to mux two power supplies (+5V or +12V) to 4 different outputs (+EXC1, ..., 4).
To generate +12V I'm using a Step Up. This step up generate +12V @ 30mA and it is limited to a 40mA…
Are there some parameters I can change in the models for the ADG408/ADG409 parts to match how an ADG1408/ADG1409 would operate?
I have both spice models downloaded: AGD408/ADG409
I would like to simulate ADG1408/ADG1409
Apologies for the delayed response here,
I think you are on the correct track here with the ADG1409. the first thing to think about when selecting a switch is the Supply voltage and the voltage you wish to pass.
If you are using a +/-15 V supply…
Apologies for the late reply.
If the voltage passing through the switch are withing the switch's rails, VDD and VSS (+/-7.5 V in your case), it should be okay for you to replace the CD4051 and CD4052 with the ADG408 and ADG409.
Thank you for your answer, I have already found the error, it was in the microcontroller's code. ADG1409 is really much more suitable for this application, but it is only a prototype, in final version of the device all chanels would be involved.
