To configure the Sallen-Key as a lowpass filter, populate
the R2 and R8 pads with resistors and the C3 and C4
pads with capacitors. The corner frequency and Q are
then given by:

Some applications require driving large capacitive loads.
To improve the stability of the amplifier in such cases,
replace R6 with a suitable resistor value to improve
amplifier phase margin in the presence of the capacitive
load (C9), or apply a resistive load in parallel with C9.
