TINA/Spice/OPA857: OPA857 TI simulation reference not working

Hi Art,

I can confirm that I get the same convergence issue you are seeing.

I know that you can let the transient analysis complete if you select "Zero Initial Value", as shown:

However, I cannot tell you the underlying cause?

To whom it may concern:

  Thank you for responding.

I was able to download the posted OPA857 reference simulation, and It looks like it is working.

The one thing this simulation is missing is a few pins which are present in the data sheet.  These are:

1). Test_SD

2). Test_In

  These are crucial in making the part work in real life.

That is, as stated in page 4 of the data sheet, for normal operation:

Test_SD = 0V

Test_In = 3.3V

Can you please update these two pins in the simulation model?

Thanks

Art
