9.2.2 Active Filters
The OPA836 and OPA2836 devices are good choices for active filters. Figure 9-15 and Figure 9-16 show MFB and Sallen-Key circuits designed using the WEBENCH® Filter Designer to implement second-order low-pass Butterworth filter circuits. Figure 9-17 shows the frequency response.
Other MFB and Sallen-Key filter circuits offer similar performance. The main difference is the MFB is an inverting amplifier in the pass-band and the Sallen-Key is noninverting. The primary advantage for each is the Sallen-Key in unity gain has no resistor gain-error term, and thus no sensitivity to gain error, while the MFB has better attenuation properties beyond the bandwidth of the operational amplifier.
