WEBENCH® Tools/THS3491: THS3491

Thanks, the model works fine.

Is there a document for "THS4541" detailing the error calculations - >  error budget 

From calculations I made from the accepted equations (Vos ,Ib, bias ) the results do not align with the SPICE electric model

Tnx.

Hi Itay,

the Spice Model only provides typical values for the input offset voltages and input bias currents.

Can you post a schematic or your TSC-file, if you have?

Each of the 3 input DC error terms is also bipolar around 0 for the CFA, The model must also pick a polarity for each of these which is frankly somewhat random. The typ output DC error for the TINA model should be within the worst case range, but only representative.
