I downloaded the THS4303spice model, and connected the components in ADS to simulate the schematic diagram.
However, the voltage and current cannot match the simulation results during the actual machining test.
For example, the simulated output voltage is 121mV, but the output voltage will become -0.71V during testing.
I follow the power supply method recommended in the manual to power the op amp.
I don’t know where the problem is, or the model itself is not accurate enough.
Thank you for help!
