Hi,
I have downloaded the OPA544 spice file from texas instrument and have simulated the circuit successfully. But the result is a bit weird. Please have a look with the attached file. Why the output voltage of the operational amplifier is not identical as the input voltage. The Vin is the input voltage of the first amplifier while the V(n002) is the output voltage of the amplifier. The result was really far away from my expectation.
Please advice. Thank you very much.
Best Regards,
