Other Parts Discussed in Thread: TINA-TI, , OPA277, OPA350, OPA378
Tool/software: TINA-TI or Spice Models
Dear all,
one of my customer has found discrepancy between TINA and SPICE model the AC simulation of the OPA4277.
The circuti is very simple, it is a Sallen Key filter.
I've attached the comparison and the Spice model used by the customer.
Can you please double check ?
regards,
Domenico
