RECOMMENDED ANALOGUE LOW PASS FILTER
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 105.26kHz and a droop of 0.15dB at
20kHz. The typical output from the WM8523 is 2.1Vrms – when a 10kΩ 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.
