Tool/software:
Hi, I'm using ALM2402F-Q1 for automotive application and Vs set to 12V. During simulation op-amp is saturating at 11V although ALM2402F-Q1 is rail-to-rail op-amp. However, it does not saturate during hardware verification test. Could you please help me to understand motivation behind saturating during simulation but not during hardware verification test?
Hi Jayal,
Sorry for this complication.
We have recently discovered a slight abnormality in the swing to rail performance for the ALM2402F-Q1 and ALM2403-Q1 SPICE macro models. This error is predominately on the V+ output side, but both sides of the claw curve are overly cautious regarding swing to rail performance.
We are currently working to revise the models to improve accuracy. I am happy to review your simulation files to verify that this disparity is from an inaccurate claw curve in model.
The EC table is the best resource to verify performance:
Thanks,
Jacob
