Hi,

 
Is the leads-off detection incorporated in the spice model of the AD8232?

 
If yes, what's a good way to test leads off?

 
I tried by disconnecting the LA and RA but I did not see a change in LOD+ and LOD- in my SPICE simulation.

 
Thanks and best regards,

 
Charlie

    Hi Charlie,
    
 
    Sorry for the inconvenience but the lead-off detection was not modeled on the AD8232 spice model. May I know why do you want to simulate the lead-off function? There is a good discussion of this at page 18 of its datasheet. Let us know if you have any question about it.
    
 
    Best regards,
    Emman
