Hi I am using the ADG1211 is my application board simulation ( downloaded the spice model for AD website). When the switch is off that time I am seeing 500nA of leakage but the data sheet says that it is few pA. Can anybody help me about this.
I will look into this and get back to you as soon as possible.
What simulation tool are you using? Also is it possible to see your simulation circuit?
I am using LTSpice.
Here is the circuit
I am using the LTSpice. Will share the circuit personally.
The leakage seen could have been caused by the primitive switch models (SMOD 1 to 7). As a quick fix, try to change ROFF from 1E11 to 1E12 and start from there.
Please see figure below.
