Hello,
Are the input bias currents modeled in the OPA837 spice model? According to the notes in the model, the bias currents should be modeled.
However, the simulation shows bias currents of ~17uA. According to the datasheet the bias currents should be ~300nA.
Am I missing something?
Thank you in advance,
Alex.
Hello Michael,
How do you suggest to proceed?
The model is not very usable due to offset voltages caused by the bias currents. Can I just remove the 2nd .SUBCKT from the current model? Can you release an updated model?
Thanks again.
Here is the closest to release model I can find, with the Ib and Ios magnitudes right and polarity flipped on the Ib,
Note all theses DC things are typs in the model with quite a physical spread around those.
