Preliminary data sheet
13.4 Differential input
13.5 Single-ended input
Table 13.
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 V
Processing (Audio DSP)).
The input configuration for a single-ended ‘in’ application is illustrated in
