RELEVANT APPLICATION NOTES
w
Figure 41 Recommended Analogue Low Pass Filter (one channel shown)
An external single-pole RC filter is recommended if the device is driving a wideband
amplifier. Other filter architectures may provide equally good results.
The filter shown in Figure 41 has a -3dB cut-off at 96.5kHz and a droop of 0.2dB at 20kHz.
The typical output from the WM8523 is 2.1Vrms – when a 2kΩ load is placed at the output of
this recommended filter the amplitude across this load is 1.99Vrms.
The following application notes, available from www.wolfsonmicro.com, may provide
additional guidance for use of the WM8523.
