Figure 31 Recommended 1st Order Low Pass Filter
Note: Capacitors should be COG dielectric.
An external single pole RC filter is recommended for each channel (see Figure 31) if the device is
driving a wideband amplifier. However the WM8522 does contain an internal low pass filter which
should be adequate in most applications.
