184.108.40.206.4.3 Step 3: Additional Low-Pass Filter
Ra must be at least ten-times smaller than RI. Set Ra = 1 kΩ
Substituting 10 kHz for fc(LPF) and solving for Ca:
Equation 31. Ca = 160 pF
Figure 33 is a bode plot for the band-pass filter in the previous example. Figure 38 shows how to configure the TPA6211A1-Q1 device as a band-pass filter.
