I need a simulation model for ADG1408 (lower RON). I have the model for an ADG408.
Can anyone help with changing RON?
I am afraid, but we don't currently have models for the ADG14xx series of devices.
Further to your circuit design, we have some information regarding the use of multiplexers in PGA designs on page 16 of the following:
There is more to a SPICE model than the On resistance. It would not make an appropriate model of the ADG1408, by updating the ADG408 model on resistance.
What circuit are you trying to simulate?
I'm simulating a selectable gain circuit that uses a ADG1411 that switches the feedback resistor of an op amp.
I don't think Ron will affect this too much but I might use the switch in another circuit and need a sim model.
I actually going to use an ADG1412 because logic high closes the switch.
Can you help with a sim model for this?
