Hi Team,
Why does customer simulate the phase of the OPA855 open-loop gain curve from 180°? But the datasheet starts at 0°
And the open-loop gain is 76dB in the datasheet. Customer found that it is also related to the output dynamic range of the op amp configuration. The dynamic range is lower, and the open-loop gain drops a lot.
Customer's simulation configuration is the same as that in the datasheet. The signal is given from the reverse input of the op amp. It should be 180° in principle.
