Just a FYI, some op amps have lower distortion in inverting mode than as
a follower. This is not intuitively obvious since a follow has maximum
feedback, which would imply the best linearity. However the distortion
as a follower is due to the common mode rejection of the op amp. That is
the inverter has the front end differential pair at a virtual ground
while the follower moves the differential pair with the signal.
