Lowpass Sallen-Key Filter

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:

fC = 2π

1

R2 × C3 × R8 × C4

Q = R2 × C3 × R8 × C4

C4(R2 + R8)

Highpass Sallen-Key Filter

To configure the Sallen-Key as a highpass filter, populate

the C3 and C4 pads with resistors and the R2 and R8

pads with capacitors. The corner frequency and Q are

then given by:

fC = 2π

1

CR8 × RC4 × CR2 × RC3

Q = CR8 × RC4 × CR2 × RC3

RR3(CR2 + CR8)

Capacitive Loads

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.
