ACTIVE FILTERING
Low harmonic distortion and noise specifications plus high gain and slew rate make the OPA363 and OPA364
optimal candidates for active filtering. Figure 31 shows the OPA2363 configured as a low-distortion, 3rd-order
GIC (General Immittance Converter) filter. Figure 32 shows the implementation of a Sallen-Key, 3-pole, low-pass
Bessel filter.
