NOTES: (1) Frequency response can be strongly influenced by PC board parasites. The OPA4650 is nominally compensated assuming 2pF parasitic load. The
demonstration board, DEM-OPA465xP, shows a low parasitic layout for this part. (2) Slew rate is rate of change from 10% to 90% of output voltage step.
