Pin 5 in the ADG5419 is not internally connected so 5V could be presented to pin 5 of the ADG5419.
Unfortunately, the ADG5419 is not available SPICE model. You may try to use the ADG1236's SPICE model as a substitute and start from there.
Please note that the ADG1236 switch parameter values are not identical to that of the ADG5419.
Thank you David for the 2 fast reply
I've to use it in the in configuration B).
I'm going to check also ADG5419
Yes the ADG1408 and the ADG1419 are based on the same technology.
The ADG5419 has an internal VL generator that is used to power the input buffer at a lower voltage so you can use a lower digital logic voltage without significantly impacting…
It is possible that you are triggering a latch-up event. You could try to prevent this by putting a schottky diode from Vss to Ground to prevent Vss going 0.7v above Ground. Alternatively you could look at the ADG5419 Latch up immune version…
I'm looking for a switch which controlled by a MCU(3.3V) to control another high voltage power source(around 30V) on and off. I checked your product list and checked some datasheets. I have several questions on the analog switch.
1. For instance…
What is Latch-up and how are these parts immune to it?
