Dear sir
I experiment a different behavior regarding input bias current in AD8675 amplifier according models I use with LTSPICE.
When I simulate the AD8675 component using the model provided with LT SPICE XVll software, I get perfect match with datasheet regarding current in input of the amplifier (typically 500pA) .
When I simulate AD8675 component using the model provided on the website of AD, ( file ad8675.cir) I get a current in input of the amplifier that is 10 times higher than the datasheet (6nA).
Why there is a such difference. on What model I can rely?
Best regards,
Bruno
