Other Parts Discussed in Thread: OPA4172, OPA4131, OPA4132
Dear Specialists,
My customer is simulating TL3474 and has a question.
I would be grateful if you could advise.
---
When I simulated the pulse response with the P-Spice model of TL 3474, although the specified slew rate of TL 3474 is 10 V / us, it is only about 1.6 V / us.
I'd like to know the reason why, simulation model or something.
Simulation model was obtained from TI's WEB, could you please see below.
---
I appreciate your great help in advance.
Best regards,
Shinichi
