Some more questions about the amplifier OPA551:
The data sheet says that pins 1 and 5 should not be connected to negative supply. But the layout for both PDIP and SOIC shows connection between pins 1-4-5. How much of a factor can this be with my performance issue?
Also if I intent to use the OPA551 as a voltage follower, I plan to connect the output directly to the inverting input in my non inverting configuration. How practical do you think this technique will be?
