The 100Hz noise voltage spec in the data sheet data table does not agree with the noise curve shown in Figure 1.
Thank God TI finally has titled its data sheet file "opa1664.pdf" instead of some incomprehensive collection of alphanumerics as TI has done up until now. In the past a user who downloaded a TI data sheet would have to re- title it if he ever wanted to find it again.
This looks like a nice amplifier. It is unusual that an op amp has THD+N as low in its non-inverting mode as it does in inverting; I suppose this may be due, in part, to its very high common-mode rejection. Speaking of CMRR, the data table should show a frequency associated with that spec.
