Figure 4-14 is a second-order Sallen-Key low-pass
filter with Chip Select. Use the Filterlab
Microchip to determine the R and C values for
op amp A’s second-order filter. Op amp B can be used
to add a pole-zero pair using C

The low-pass filter shown in Figure 4-15 does not
require external capacitors and uses only three exter-
nal resistors; the op amp’s GBWP sets the corner fre-
quency. R
is used to set the Q. To avoid gain-peaking in the
frequency response, Q needs to be low (lower values
need to be selected for R
bandwidth varies greatly over temperature and
process. This configuration, however, provides a low-
cost solution for applications with high bandwidth
requirements.
