Part Number: OPA2810
Other Parts Discussed in Thread: TEST

Hi Team, we would like to seek your assistance on the graph translation since the plot starts near 180 instead of 0.

Hoping for your inputs.

Thank you.

    Well Mark, 

    This curve is usually simulated from designer, the easiest way to set this up is with the V+ node grounded and run an inverting Aol test, that gives an initial phase of 180deg - just a small mistake I suspect,
