SN10502: Does the PSpice model contain accurate parameters for noise measurement simulation using Tina?

Hello Lauren,

It looks like the voltage noise in the model is greater in the lower frequency range, but is comparable to the datasheet for broadband noise. Current noise is also greater in the model than what is shown on the datasheet. Here are the TINA models to measure both:

Voltage_noise.TSC

Current_noise.TSC

2500.Voltage_noise.TSC

So Hasan, 

Those models of the SN are encrypted, but these are just relabeled THS4226 parts. That model is in TINA V11 library and opens fine - looks like a very nice transistor level model, seems to be simulated pretty close to PDS plot actually,
