TINA/Spice/OPA657: still trouble with OPA657 noise model in TINA-TI Version 9.3.150.328 SF-TI

Part Number: OPA657

Tool/software: TINA-TI or Spice Models

Dear Support,

I just downloaded the latest available TINa-TI v9 from TI web site and I run a noise simulation on OPA657,

just to check the noise model agrees with data sheet (both voltage noise and current noise OPA657_noise_test.TSCvalues).

While voltage noise is fine, noise current seems wrong by order of magnitudes.

Please see the attached file.

Am I doing something wrong ?

Please advice.

Kind Regards,

Alberto
