Same as above but with improved noise performance due to
increase in dynamic range. Headroom/settling time requirements
of
±
5 op amp should be evaluated.

19, 20
Optimum noise performance, excellent THD performance, often
requires low distortion op amp with VCC > +5 V due to its head-
room issues.
