Stereo operation: to avoid acoustical phase differences, the inputs should be in
anti-phase and the speakers should be connected in anti-phase. This configuration:
– minimizes power supply peak current
– minimizes supply pumping effects, especially at low audio frequencies
Mono BTL operation: the inputs must be connected in anti-parallel. The output of one
channel is inverted and the speaker load is connected between the two outputs of the
TDA8922C. In practice (because of the OCP threshold) the output power can be
boosted to twice the output power that can be achieved with the single-ended
configuration.
The input configuration for a mono BTL application is illustrated in
