running into current limiting. Current limiting (clipping) will avoid audio holes, but it causes
a sound distortion similar to voltage clipping.
For a flat-frequency response (second-order Butterworth filter) it is necessary to change
the low-pass filter components L
impedance.
Table 12.
For a high common-mode rejection ratio and a maximum of flexibility in the application,
the audio inputs of the application are fully differential.
The input configuration for a differential-input application is illustrated in
When using an audio source with a single-ended ‘out’, it is important to connect the IN1N
from the application board to the VSS/GND of the audio source (e.g. Audio DSP).
The input configuration for single-ended ‘in’ application is illustrated in
