4.8.3.4
Figure 4-12 shows a lossy non-inverting integrator that
is buffered and has a Chip Select input. Op amp A is
configured as a non-inverting integrator. In this config-
uration, matching the impedance at each input is
recommended. R
at frequencies << 1/(2 R
integrator (it has a finite gain at DC). Op amp B is used
to isolate the load from the integrator.

Integrator with Chip Select.
4.8.3.5
Figure 4-13 uses an active compensator (op amp B) to
compensate for the non-ideal op amp characteristics
introduced at higher frequencies. This circuit uses
op amp B as a unity-gain buffer to isolate the integra-
tion capacitor C
itor with low-impedance source. Since both op amps
are matched very well, they provide a high quality
integrator.

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