set the gain, and C
1
through C
5
are supply bypass
capacitors. C
3
is optional; it adds a bypass between the supplies that improves distortion performance for
some models. L
1
and L
2
are ferrite chips that can reduce interactions with the power supply at high
frequencies. If not desired, they can be replaced with 0
Ω
resistors. R

and C

are optional
components that support op amps with special functions.
For single-supply operation, do not connect L
2
; otherwise, the –V
S
input to P
1
would be at ground
potential.
